I'm a simple chips enjoyer (or crisps if you're a Britbong). Something salty to balance the sweet jelly. I usually eat crunchy peanut butter, so it's already a little savory.
Lightly toast one side of each slice of bread for the outside of the sandwich (or the inside depending your preference).
Place a slice (shaved from a block) of cold cheddar cheese in between the PB and J. You can vary the thickness of the cheese slice depending on the texture you'd prefer.
2qty toasted pb&j sammies, a bowl of apple sauce & a can of orange soda. If lunch was a last meal that'd be my last meal lunch menu. You eat 1 Sammy, then apple sauce, then drink half of can, then eat 2nd Sammy and top off the orange soda.
Pb&j burritos are far superior to sandwiches, you can get more filling and less “breads”. I typically eat mine with a small handful of chips (harvest cheddar, or the red bag of sun chips may be my favorite with pb&j) or some sort and some dill pickles.
Heat a flour tortilla so it is soft and pliable. Add peanut butter, then add jelly (you may want to stir the jelly in a bowl so it is not lumpy, if you mix it on the tortilla it can mix the pb with the j and some do not like that, it does not bother me personally). Fold over the left and right sides slightly, and then roll it up, and enjoy!
