Preheat oven to 350 F degrees.

Heat oil in a large skillet over medium high heat. Add the onion and cook until softened, about 5-7 minutes. Stir in garlic and cook additional minute.

Stir in beef and cook. While cooking, break up the meat with a wooden spoon and cook until no longer pink, about 5-7 minutes. Add the Worcestershire sauce, chili powder, cumin and 1 1/2 cups crushed tomatoes. Cook 3-5 minutes.

In a large bowl add the beef mixture, 3/4 cup cheese, parsley and cooked rice. Season with salt and pepper to taste.

Place remaining 1/2 cup crushed tomatoes on the bottom of a 9x13 baking dish. Divide the filling evenly among the peppers. Cover with foil and bake 30 minutes in preheated oven.

Remove foil after 30 minutes and sprinkle with the remaining cheese. Bake until the cheese is bubbly and browned, about 5-10 minutes.

Serve immediately and enjoy!
