Step 1

In a large skillet, brown the ground beef, then drain excess liquid. Add the bell peppers, onion, garlic, Italian seasoning, salt and pepper to your skillet. Continue cooking over medium heat, until the onion is translucent. Remove from heat.

Step 2

Stir in the diced tomatoes, tomato paste, Worcestershire sauce and beef broth. Turn off heat and stir in the rice.

Step 3

Transfer the beef and rice mixture into a 9x13 inch casserole dish and cover very tightly with foil. Bake at 375°F for 35 to 40 minutes.

Step 4

Remove the foil and sprinkle the shredded mozzarella over the top of the casserole. Return to oven and cook an additional 5 to 10 minutes, until the cheese has melted.
