Heat the olive oil in a large skillet over medium heat. Once heated, add in the garlic, red pepper flakes and let cook until fragrant, about 30 seconds. Add in the zucchini noodles and cook for 3-5 minutes or until al dente/cooked to your preference.

Once cooked, stir in the parsley, lemon juice/zest, tuna and olives. Toss to combine and heat up the tuna.

Serve.
