This is an easy dish to make on the stovetop with only one pan to wash. From an old Betty Crocker cookbook. I leave out the pepper or mushrooms if I don't have them. Can throw in a can of corn if you wish.
Cook and stir beef, onions and peppers in a skillet or Dutch oven until beef is light brown, drain.
stir in rest of the ingredients except for the cheese.
heat to boiling, reduce heat. Cover and simmer, stirring occasionally until spaghetti is tender, about 30 minutes. (Add water during cooking if necessary) I usually have to add water or just put in more at the beginning.
