Grandma Bradley's Sloppy Joes
(70+ year old recipe)
1lb ground beef (turkey or chicken works well also).
1 Lg onion diced
3/4 cup ketchup
2 Tbsp Yellow mustard (spicy is nice too)
1 Tbsp white vinegar
1 Tbsp Worcestershire sauce.
1 Tbsp sugar.
Brown beef with onions add remaining ingredients simmer 1 hour. Or all day in crock pot.
I add green pepper sometimes to change the flavor a bit. My husband loves this over rice.
