Start with ham. Make a tight roll. Roll the bologna strip around the ham, and so on. Save the pepperoni for last. Pierce with a toothpick to hold the roll together. Serve to the kids as an appetizer instead of lunch. Or, in lieu of a sandwich in the school lunch for those kids who don't like sandwiches because of the bread. Just drop them in a baggie. They can be made with any combination of cold cuts.
