We've all had peanut butter on celery, now here is peanut butter with sliced celery in a sandwich! It's delicious, and much less messy in a lunchbox. You can see I used a round scalloped cutter to shape the bread (saving the trimmings, which have a hole in a slice of bread, for "eggs in toast" on the weekend).
I sent these sandwiches with cashew clusters, Back To Nature Oreo style cookies, and pretzels fill in the spaces around the sandwich in the Lunchbot tin. I also sent applesauce on the side- it would not fit in the tin.
