I have been making these for years. My son loves them! They also freeze well. I do the dough in the bread machine and it has come out perfect every time of the many dozens I have probably made them.
Shortcut: Just brown ground beef and onion and garlic. Put it on the dough circles. Squeeze ketchup over and top with cheese.
You also can use other fillings. Like chicken with cream of chicken soup and green onions we like. Or ham and cream of mushroom with diced cooked potatoes.
This is one of the top 10 recipes ever to come out of TOH.
