Shouldn't be too hard.
Canned pork and Beans, Honey, brown sugar, ketchup, onion, bacon, Worcestershire sauce, vinegar(if needed for a bite).
Careful with the honey, it can go really sweet fast. If you want a bit of old time richness, cut back on the brown sugar and add black strap molasses.
Place in a baking pan and bake slow so it thickens up...
