Pam's Perfect Baked Beans

1 pound hamburger
1 pound bacon -- diced
1 small onion -- chopped
2 28 ounce cans baked beans -- Bush's
2 15 ounce cans pork and beans
1 15 ounce can tomato sauce
1/4 cup mustard
1/4 cup brown sugar
salt to taste

Brown hamburger, onion and bacon. Drain off any fat remaining and add other ingredients. Put in a Casserole dish and bake at 325° for 40 minutes, uncovered


NOTES : These are really good baked beans, because of the hamburger and bacon, it could be served as a casserole too. Yummy!
