I got this recipe from combining one a friend gave me with one of Suzanne Somer's recipes to give us the combination we liked.
This is a protein/fat recipe.
2lb ground beef (or turkey)
1 small onion, diced
2 cans tomato sauce, 8 oz each
2 packets spaghetti seasoning mix (I use a homemade mix I keep on hand)
diced green chilies, optional
parmesan cheese (I used about 1/2 cup)
mozzarella or colby jack cheese, shredded
6 med to large green bell peppers
Preheat oven to 350 degrees. Brown beef and onion in skillet, drain. Stir in green chilies, tomato sauce and seasoning mix. Stir and heat through, stir in parmesan cheese. While beef is browning, cut off tops and gut the peppers. Place in 9x13 in pan. When meat mixture is heated through, spoon mixture into peppers. Bake for about 25 minutes, top with shredded cheese and bake an additional 5 minutes or until cheese is melted and bubbly.
You can also cook these in the crockpot on high for 3-4 hours or low for 7-8 hours.
