Begin by heating your large skillet over medium heat. Add the diced onion and sauté until it becomes translucent, about 3-4 minutes. Stir in the minced garlic and cook for an additional minute until fragrant.
Add the ground beef to the skillet. Use your wooden spoon to break it apart and cook until it's browned and no longer pink, approximately 5-7 minutes. Drain any excess fat if necessary.
Stir in the chopped green and red bell peppers, followed by the diced tomatoes, white rice, beef broth, tomato paste, Italian seasoning, salt, and black pepper. Mix well to combine all the ingredients.
Bring the mixture to a gentle boil, then reduce the heat to low. Cover the skillet and let it simmer for 15-20 minutes, or until the rice is tender and has absorbed most of the liquid.
Once the rice is cooked, remove the skillet from heat and sprinkle the shredded cheese over the top. Cover the skillet again for a few minutes to let the cheese melt beautifully.
Sprinkle the skillet with chopped parsley for a fresh finish. Serve hot and enjoy this comforting Ground Beef Stuffed Pepper Skillet with your family or friends!
