  • 1 TBS olive oil
  • 2 cups diced bell pepper
  • 1 cup diced yellow onion
  • 1/2 TBS minced garlic
  • 1 lb ground beef (or ground turkey)
  • 1 1/2 TBS Italian seasoning
  • 1 tsp salt
  • 1 15 oz can tomato sauce
  • 3 cups cooked rice
  • 1 cup mozzarella cheese (divided)


  • Preheat the oven to 350 degrees Fahrenheit. Grease a 9x13 pan with nonstick spray.
  • In a large sauté pan, add the olive oil, diced pepper, diced onion and minced garlic over medium high heat and cook for about 5 minutes until the vegetables just start to get soft, stirring often.
  • Add in the ground beef and cook until it is cooked through completely. Carefully drain the grease out of the pan.
  • Add in the Italian seasonings, salt, tomato sauce, rice, and 1/4 cup of the mozzarella cheese. Stir it all together.
  • Pour everything into the prepared baking dish and sprinkle the remaining cheese over the top of the dish.
  • Cover the pan with foil and bake in the oven for about 25 to 30 minutes. Remove the foil and bake for an additional 5 minutes, or until the cheese is melted and golden brown.
  • Remove the dish from the oven and let it set for 5 minutes, then serve hot.
