Did you know that you can freeze peanut butter and jelly sandwiches for school lunch? It's true! Spread peanut butter on one slice of bread. On the other slice, spread a thin layer of peanut butter to act as a barrier for the jelly to avoid seepage, then spread on the jelly. Assemble the sandwich and freeze. In the morning, put the frozen sandwich in your kid's lunch box or bag and the sandwich will be perfect and ready for eating at lunchtime!
