This is not quite as simple as a bag of cashews and raisins, but it doubles as a fun activity if you let your child do the final assembly. Sometimes "playing" with food is encouraged in our house.
Apples, Raisins, and Peanut Butter
One medium apple, cored and sliced
Two tablespoons of peanut butter
A handful of raisins
Depending on the age and preference of you child, you can either assemble these ahead of time or let you child do the assembling. Make snack time fun!
