I found this interesting recipe in a 1946 cookbook! I thought you might enjoy seeing something from the past! I love baked beans but I've never made a sandwich with them until now:
Baked Bean Sandwiches
1 lb. can baked beans
3 strips crisp bacon, crumbled
2 TBSP tomato catsup
3 TBSP pickle relish
16 slices whole wheat bread
Mash baked beans until smooth. Blend in catsup and relish. Spread 3 TBSP filing on each of 8 slices of bread. Scatter crumbled bacon over each.; top with the other slices of bread.
Side Note: My mom adds cheese to everything! So thought I would . . . melted cheese makes it even better and keep some extra bacon to add on top too!
