Remove tops and then the seeds of the pepper.

Place on a large baking pan.

Saute onion and pepper in lightly oiled skillet until tender.

Set aside.

Brown meat and drain.

Add onion, pepper, cooked rice, diced tomatoes, tomato paste, egg, and garlic to meat; mixing well.

Spoon meat mixture into green pepper and place in a 350 degree oven for 40 minutes, remove from oven and sprinkle with grated Parmesan and mozzarella cheese.

Return to the oven for 5 minutes until the cheese has melted.

For those you plan to freeze, do not add the cheese at this point.

Remove from oven and allow to sit for five minutes prior to serving.

Allow to cool completely before wrapping in parchment paper and then foil for freezing.
