DH doesn't like green peppers, so I use red or yellow (which reminds me, they are on sale this week and I should do up some dinners for the freezer). I saute onion, celery, the chopped pepper tops, shredder carrot (and/or zucchini) lots of garlic and sometimes even some chopped spinach (it was a great way of hiding those dreaded veggies from the kids!), add the browned ground beef and diced canned tomatoes. I sometimes add a can of Rotel too. Let it simmer, season to taste, stuff it into the peppers and then top with whatever tomato sauce I have, again adding extra seasoning. Serve over brown rice.
