1 (16 ounce) package Barilla uncooked rotini pasta
1 (25 ounce) jar marinara sauce
3 cups water
1 (14 ounce) package fully-cooked miniature (cocktail-size) meatballs (if using frozen meatballs, make sure that they are completely thawed before using)
2 cups Kraft shredded mozzarella (or Italian blend) cheese
Optional: Parmesan cheese and fresh chopped herbs (such as basil, oregano, and parsley) for garnish
Preheat oven to 425 degrees F.
In a large baking dish, stir together uncooked pasta, marinara sauce, water, and meatballs. Cover tightly with aluminum foil and bake for 30 minutes.
Sprinkle mozzarella over the top and bake uncovered for 10 more minutes (or until cheese is melted and pasta is tender).
