This recipe is the best way to preserve green beans. (in my opinion:)) They have lots of flavor & are so convenient to just heat up whenever you need them.
16 slices bacon, fried
1 onion, chopped
3 1/2 C ketchup (2 20 oz. bottles)
1/2 C mustard
2 C brown sugar
2 tsp salt
7 quarts green beans
Mix all ingredients together & put in jars. Process for 3 hours in hot water or 25 min. in pressure canner.
