Preheat the oven to 425 degrees. Grease a large muffin tin with cooking spray.

Heat oil in a large skillet over medium-high heat. Once oil is shimmering, add in the potato noodles. Season with salt, pepper and garlic powder and toss. Let cook for 7-10 minutes or until cooked through and lightly browned. Transfer to a medium mixing bowl. Let cool for 2 minutes.

Add in the eggs to the bowl and toss thoroughly to combine. Pack the potato noodles into the muffin holes, trying your best to create a cavity in the center. Bake in the oven for 15 minutes or until potato mixture has set.

While potato cups bake, pour the tomato sauce into a small skillet and bring to a strong simmer. Add in the meatballs and let heat while potato cups cook.

When potato cups are done, remove and align on a platter.

If serving immediately, place one meatball on top of each potato cup and top with extra sauce, if desired.

If not serving immediately, transfer the cooked meatballs to a serving bowl along with pasta tongs. Let guests make their own meatball cups and serve themselves!
