Wash apples, core and slice each apple into 8 thin rounds. (No corer? No problem! Just thinly slice the apple and follow the rest of the instructions).
Place approximately 1/2 tablespoon of nut butter onto slice, place 1/8 cup raisins, 1 teaspoon chopped walnuts. Top with another apple round. Repeat until you have 8 apple sandwich snacks!
