Preheat the oven to 375 degrees. Grease a nine-by-13-inch baking dish, and set it aside.
Be sure to start your rice, cooking it according to package instructions. You’ll want to end up with two cups of cooked rice.
Heat a large skillet over medium heat. Add the onions, peppers and ground meat to the pan. Brown the meat, breaking it apart as you go. When the meat is done and the vegetables are cooked through, drain off any accumulated fat, and add the garlic to the pan.
Saute until the garlic is fragrant, about two minutes, and then dump in the diced tomatoes (don’t drain them), tomato sauce, broth, oregano, basil, parsley, paprika, salt and pepper and your prepared rice. Stir to combine.
Once everything is mixed together well, pour all of it into your prepared baking dish. Cover the pan with foil and bake it for 25 minutes.
Remove the foil, sprinkle the top with cheese and bake for an additional 10 minutes or until the cheese is melted and is just starting to brown.
Let the casserole cool for 10 or 15 minutes before serving.
