This recipe came from a recipe that showed up on my facebook page and I changed it some to fit what I had at home.
2 lbs hamburger
1 green pepper chopped
1 red pepper chopped
1/2 onion chopped
2 T. Worcestershire sauce
Salt and pepper
6 sub rolls
Shredded cheese (8 oz) of your choice- I used an Italian blend of 4 cheeses
Put a little butter or margarine in the pan with the chopped peppers and onion. Cook them just a little while-- you do not have to cook them until they are completely soft just get them about half cooked. Add the hamburger, scramble and cook it until completely done, drain grease as you are cooking. Add the Worcestershire sauce and salt and pepper. Cut subs if not already cut and fill with the hamburger mixture, add cheese on top. Put in the oven just until cheese is melted and buns are lightly toasted.
