This is actually in the Joy of Cooking as a recommendation for a peanut butter + something sandwich.
Here's how I did mine:
2 slices fresh egg bread
1 T peanut butter
3 sliced crisply cooked bacon
1 T (or less) hot pepper jelly
Spread peanut butter on one slice of bread. Don't layer it too thick. Spread hot pepper jelly on other slice. Again, not too thick. Break up bacon slices to fit on one of the slices. Slap the two slices together and ENJOY!
Surprisingly, it's a tasty combo.
