Spaghetti and Meatballs Muffin Bites

Bring a large pot of lightly salted water to a boil. Cook spaghetti in the boiling water, stirring occasionally, until cooked through but firm to the bite, about 7 minutes. Drain and toss in a bowl with olive oil, then refrigerate until cool, about 15 minutes.

Preheat the oven to 375 degrees F (190 degrees C). Spray a 12-cup muffin tin with cooking spray.

Toss cooled spaghetti with 1 cup Parmesan cheese. Divide spaghetti between the prepared muffin cups, arranging noodles in each cup to create "nests" for the meatballs.
