What's wrong, Rachel Ray hasn't shown you how to make these??
Stuffed Bell Peppers
Cut off tops of 4 medium green peppers; remove seeds and membrane.
Precook green peppers in boiling salt water about 5 minutes; drain.
Cook 1 pound of ground beef (with seasonings you like) and 1/3 cup chopped onion till meat is lightly browned. Add one 1 pound can tomatoes (i just use a small can of tomato sauce) 1/2 cup water, 1/2 cup uncooked rice. (I add in tony's and garlic.)
Cover and simmer till rice is tender, about 15 minutes. Stir in about a cup of shredded cheddar cheese. Stuff peppers and stand them upright in a baking dish. Bake uncovered at 350 degrees F. for about 20 to 25 minutes (at the last 10 minutes or so, cover with more cheese) and voila!
