Normally I make rollup/sushi sandwiches with tortilla shells (it's that whole flat and flexible thing.) This time I used two pieces of multi-grain bread with the crusts cut off. Microwave the bread for 10 seconds to make it really pliable.
Stack one slightly on top of the other, width-wise.
Roll it flat with a rolling pin.
Spread your toppings of choice - peanut butter & jelly
