1.Preheat oven to 375 degrees, have a large casserole or baking dish sprayed with cooking spray. Set aside.
2.Cook pasta to al dente. Try not to over cook and make too soft. Drain and pour into casserole dish.
3.Pour sauce over pasta and gently mix in.
4.Microwave the meatballs just until they are not frozen solid. Set aside while you add the other ingredients.
5.Toss in parmesan, grated cheddar or mozzarella, along with garlic, onion, and turmeric powders. Mix gently. Add in the peppers. They can be frozen or microwave just a minute or two to soften them up a bit.
6.Fold in the meatballs. Mix gently not to break them apart. (Save a few for garnishing the top of casserole as shown in photo)
7.Bake for about 30 to 35 minutes until hot. You will probably see some bubbling. Take out, let sit on the counter for a few minutes. Sprinkle a little more Parmesan, this is optional.
