Step 1

Preheat oven to 375° F and grease a 9x13 baking dish.

Step 2

Mix together the uncooked instant rice, jar of pasta sauce, can of undrained diced tomatoes, water, and any additional seasoning you'd like to use. Place the mixture onto the bottom of your prepared dish (you can also mix everything together directly in the dish if you'd like).

Step 3

Place the frozen meatballs on top of the mixture and cover tightly with foil. Make sure the foil is covering the entire dish so that the rice can fully steam and cook.

Step 4

Bake in the center rack of your oven for 45 minutes.

Step 5

Remove the foil and evenly sprinkle on your cheeses. Bake again, uncovered, for 5-10 minutes, or until the cheese is melted to your liking.
