When my younger son was Cub Scout age, I was the den mother for his little den of Cubs. In one of my cookbooks is a piece of paper that I obviously copied for the boys, labeled "Easy Snacks for Healthy Cub Scouts." Here are a couple of the recipes that I included.
Snack on a Handle
Spear cheese cubes, meat, or fruit (pineapple, grapes, strawberries) on straight pretzels.
Core an apple. Stuff the opening with peanut butter, cream cheese, or cheese spread. Chill. To serve, clice crosswise.
Both of those still sound really good. The apple pinwheels would require a lot of adult help for little guys, but the snacks on pretzel handles would be a great "recipe" to use to show children how to prepare a nice plate of snacks for family or friends - or maybe for a Blue and Gold banquet!
Here's a book I found from Family Fun Magazine that's inexpensive and full of terrific snack ideas for kids of Cub Scout age. I like the Apple S'Mores recipe. Click to take a look inside the book, to get a "taste" of the recipes inside!
