Sesame Crusted Tuna & Avocado with Spicy Sesame Zucchini Noodles

My mother’s the best at marinading meats. Even this past weekend, there was a flurry of texts sent after a dinner at my parents’ house praising her chicken. I don’t know if she just knows a magical ratio of sauces and spices or if its her timing, but she’s a great marinader. Marinader, yup.

Personally, I’m not a great marinader. I think it’s spending many of my formative cooking years as a vegan, I never experimented much with marinades. Tofu doesn’t need much work!

Now, in my old age as a food blogger, I’m experimenting more than ever. Today, I’ll teach you a shortcut marinade that only requires one ingredient (courtesy of Bragg) that even my mother would approve of. Right, ma?

Crusting tuna in sesame seeds adds a beautiful aesthetic and crunchy texture to the fish. To get the seeds to stick, I usually use olive oil or honey, which can add up to 100 extra calories to an otherwise lean protein! The solution? A low-cal marinade!

I’ve been meaning to make a mango-flavored avocado sauce over zucchini noodles. While I started in that direction, I ended up using Bragg‘s Organic Hawaiian Dressing & Marinade to add luscious flavor to the tuna before I crusted it in sesame seeds.

What a success! This sesame-crusted tuna has never tasted this yummy. The sweetness of the mango and pineapple flavors combined with the crunch of the sesame seeds, the creaminess of the avocado and the spicy sesame flavors of the zucchini noodles are just…. well, you can imagine: incredible!

The zucchini noodles are lightly tossed in sesame oil and red pepper flakes to combat the sweetness of the marinade and add more of a zing to every bite. Honestly, without Bragg’s dressing, this dish would not have been the same. I let the tuna sit in the marinade for just 10 minutes and it makes each bite so flavorful!

Bragg is one of my favorite brands – all of their products, like my recipes, come from a healthy standpoint, like their company motto:

You are what you eat, drink, breathe, think, say and do.

This marinade contains the following ingredients:

I can’t rave about this recipe any longer, it’s time for you to make it. You won’t know what to dig into first: the tuna, the avocado or the zucchini noodles!

Ali, this looks so good! I will definitely try it. But where did you find the Bragg marinade? I have their apple cider vinegar and liquid aminos. I'm always looking for gluten free sauces and marinades!
Bragg actually sent it to me! You can find all of their products for order on!
Mmm such a healthy mouthwatering dish. Love anything avocados.
Thank you - avocado is always a go to for me!
Joanne says:
Low-cal AND filled with tons of flavor?! Sounds good to me!! It did always bother me that oil-based marinades were so many calories for so minimal flavor.

Love this recipe! I tried it with shrimp instead of tuna because the fish counter didn't have anything fresh and it was awesome! I added a light drizzle of homemade spicy mayo which really added a lot of flavor. Thanks for posting!

You do not have the amount of zucchini listed in your recipe.
Ashley says:
Just love your site and recipes! Would love for you to post the nutrition facts, but it's easy enough to figure it out. Thanks for the great ideas! My spiralizer is basically my new best friend. Made this dish tonight and it's delicious!

In the past year, we started posting nutritional information, so those recipes have them! Sorry about the inconvenience.

Hi there, Is there any alternative to the marinade? I'm in Canada and I don't believe the Bragg's is available here. Thanks!

cauliflower and carrot masala, totally normal meal on thanksgiving eve, right? 😅🥄

tomorrow we’re going to my BIL’s to hang out with Lu’s side of the family, and I’m excited to see everyone (it’s been YEARS!) and have the kids spend time with their cousins, aunts and uncles 🙏🏼

for the curry, simmer cauliflower, carrots, a jar of @mayakaimalfoods, and 2 cups of @bonafideprovisions veggie broth in a large pot for 20 minutes or until thickened to your preference. add cooked lentils, stir, and serve with jasmine rice, chutney and toasted naan. easy 30 minute meal 👏🏼 not exactly thanksgiving-friendly, but worth a share!

safe travels today and tomorrow and wishing everyone a safe and happy thanksgiving 🦃 I’m so grateful for you

rio and sol are 10 weeks old today! 👶🏻👶🏻 10 weeks! 2.5 months! let's chat.⁣ 🙏🏼

rio is much like luca. he loves to be held and needs more touch or movement to fall back asleep. he loves to stare at things in a serious way, especially high-contrast art for babies, so I love reading him books while I hold him (he's the best snuggler.)⁣

sol is my chill boy. he's a good sleeper. he smiles and loves to talk. he's squealing and making his goo-goo-ga-ga sounds all the time, I love chatting with him. he's a bit more like roma as a baby, a bit more independent. he makes the funniest faces and serves up the grimaces like luca used to.⁣

what's funny about twins is that just when you think you know their personality differences, they change - they'll swap. 🤷🏻‍♀️ and to tell them physically apart, there are two key differences:⁣
⏺ rio has a wider head and sol has a more narrow, round forehead⁣
⏺ rio weighs a full pound more than sol⁣

and yes, I have mixed them up a few times! I've been carrying one around, talking to them by name, and then all of a sudden, when I go to pick the other one up, I realize I mixed them up! 😱when they're not together or you're not looking at them straight on, it can be confusing! one of my favorite games is texting my family photos of them and saying, "who's who?!" they get it right 50% of the time, ha!⁣

so far, having twins is just so cool. it's so cool that there are two of them and they are identical! every week that goes by, their personalities shine and I am having so much fun getting to know them - and getting twice the cuddles. and yes, they do sometimes cry at the same exact time, but you just have to pause, gather yourself, and get your soothing game on.⁣ 💪🏼

I have to say, while having newborn twins and 2 other older kids at the same time has its challenges, I give a LOT of credit to those who have twins as their first baby experience - I can't imagine going into this not knowing what I already knew about raising babies. talk about overwhelming! 🤯 all moms are crushing it, but especially those first time moms with multiples - woop! bless you. 👏🏼 #identicaltwinboys #identicaltwins #monoditwins #twinmom #twinboys
