In Super Simple Lunches: Easy No-Bake Recipes For Kids by Nancy Tuminelly, it starts out in the beginning to reduceand reuse. For example, take a lunch box so as not to keep using paper bags. Store food in reusuable containers instead of plastic bags. Carry a water bottle. Then you will not have to buy drinks all of the time.

Page 25 has the recipe for tasty tuna salad. Although tuna is onle of my favorites, instead of using a tortilla or bread, this recipe calls for two (2) iceberg lettuce leaves. This would be too flimsy in a lunch box and not filling enough. However, that is just my 2 cents.
Page 28 has the directions for ham and cheese pinwheels. Although this calls for ham, which not all kids like (myself included), you could use any lunch meat to your liking. Personally, I would use pepperoni or salami to go along with the called-for mayonnaise, spinach, provolone cheese, tomato and tortilla.
The above two (2) recipes just may be what you need to mix up lunch and make it interesting.
