Instructions:

Preheat the oven to 350°F (175°C).

In a large skillet, brown the ground beef or turkey over medium heat. Drain excess fat.

Add the onions, garlic, and bell peppers to the skillet, cooking until softened (about 5-7 minutes).

Stir in the uncooked rice, marinara sauce, diced tomatoes, broth, Italian seasoning, salt, and pepper.

Bring the mixture to a simmer and cook for 5 minutes, stirring occasionally.

Transfer the mixture to a greased 9×13-inch baking dish.

Cover with foil and bake for 35-40 minutes, until the rice is tender.

Remove the foil, sprinkle the shredded cheese on top, and bake for another 10 minutes until the cheese is melted.

Let the casserole sit for a few minutes before serving. Enjoy!
