There are so many different recipes for these, some have rice in them, some have corn in them and some even have cheese in them. Mine are just plain old Stuffed Peppers. I don't measure too terribly much, but here goes.
4 to 6 green peppers, cleaned but left whole
1 1/2 lb good hamburger
1 sleeve of saltine crackers crushed
1 lg can tomato sauce (not spiced like for spaghetti)
1/2 C chopped onion
Mix the above 7 ingredients, it should not be too stiff, if needed you could add a little water if you don't have enough tomato sauce. Stuff your peppers, either bake in the oven at 350 degrees for about one hour or throw in the crock pot all day on low or 4 to 6 hours on high. When I put them in the crock pot, I like to put a can of bought tomato soup down over them, then serve them with mashed potatoes.
My hubby likes these a lot.
