Preheat oven to 350 degrees Fahrenheit.  Cut peppers in half from the stem to the bottom.  Remove the stem, inner pith, and seeds.  Place peppers on a small baking sheet and roast them in the oven for 25 minutes.

Bring rice to a boil in a small sauce pan with 2 cups of water.  Cover and simmer for 15-20 minutes until all the water is absorbed.

In a 12 inch skillet, add the ground beef, onion, garlic, salt. and pepper.  Cook until the beef is browned and onions are tender.  Drain excess grease.

In a large bowl.  Combine the beef and rice mixture.  Add the tomato sauce and 1 cup of cheese.  Mix until combined.

Pile filling into the cooked peppers.  Sprinkle with remaining cheese and bake for 10-12 minutes - until cheese is melted to your satisfaction.  Enjoy!
