This is a very popular recipe and I try to make a huge batch so they'll last longer than a day or two, but people snag one or two for breakfast the next day, some disappear in lunch bags, and there's only one or two left for an after school snack the next day.
Good thing they're easy to make.
1 c ketchup
1 c Bisquick
1 med onion, finely chopped (1/2 c)
2-3 lb ground meat (can use all beef or a blend of beef and pork, turkey, veal, or lamb)
Worchestershire sauce, salt and pepper
Use a hand mixer to combine the remaining ingredients. It aerates the meat so it doesn't pack too tight and it's much faster than by hand. Plus your hands don't get so darn cold.
Turn the meat out into a large, greased (or sprayed) sheet pan.
Form the meat into a rectangle.
I can get about 8 mini loaves per pound of meat.
