Add and place bacon and ground beef in a large, deep skillet. Cook over medium-high heat until evenly brown. Drain and set aside.
In a four-quart casserole dish, add and mix the bacon, ground beef, pork and beans, kidney beans, butter beans, lima beans, ketchup, onion, vinegar, dry mustard, and celery.
Cover and bake for an hour.
Note:
If you want to feed a crowd, simply double your recipe, sit back and watch your guests eat the most delicious beans during a picnic or potlucks.
