Here it is, straight from mom.
Baked Beans
2 cans Pork and Beans (Van Camp's are best)
1 can Kidney beans (or Pinto beans)
1 can Butter Beans (Bush or store brand have large lima beans), but, if you don't really like them, you can use Navy Beans.
1 pound ground beef
6 or 8 slices of bacon
1 onion (chopped)
1 bell pepper, chopped (can be omitted)
1/2 cup ketchup
3/4 cup dark brown sugar
2 teaspoons dry mustard
2 teaspoons vinegar
1/2 to 1 teaspoon Worcestershire Sauce
1/2 teaspoon Garlic Salt or 1/4 teaspoon garlic powder
Can bake in the oven at 350 for 40 mins or all day in the crock pot.
Directions:
Cut the bacon in small pieces and brown. Remove and set aside. In same
skillet, brown the onion and ground beef (you can remove part of the
bacon grease if there is a lot in the pan).
Add the bacon, onion and beef to the crock pot.
Drain some of the liquid off the kidney beans and the butter beans. You
can mix everything up together in the crock pot at this point. I
usually mix in the pan where I cooked the meat and let it warm a bit
before going into the crock pot.
You can taste and see if you think you need any more garlic salt, etc.
Also, I usually add about 1/4 cup of barbeque sauce when I add the
ketchup.
