And, there s always the old standby of browned and scrambled ground beef. Vegetables Use a mix of vegetables, some for seasoning, and some for bulk. I almost always add a small onion and usually some garlic. Bell peppers, celery, and chilies are also good seasoning vegetables. Mushrooms, broccoli, frozen green peas, whole kernel corn, green beans, water chestnuts, and carrots are common additions.
Canned tomatoes work well with the ground beef use the juice and cut back on the milk.
Cheese Cheddar, American, Jack, Swiss, Colby or most any of the hard or semi-hard cheeses work well. Cottage cheese, cheese spreads, cream cheese, ricotta, and other soft cheeses are fine for the filling, but not for the topping. Crushed pretzels, croutons, or dry bread stuffing mix also work. This is also a good place to use crumbled day old biscuits, English muffins, bagels, or hard rolls. Share your favorites with us .
