I made these for my Annual Post Holiday party, and they were super easy and fun. They would be great in lunches (if your kid likes kalmata olives! Mine are not convinced. The Boy tried to eat the feta off from all of them...) More of an idea than a recipe, but here you go!
Pitted Kalmata olives
cubed feta cheese (or a small block of feta, cubed)
Place ingredients on small skewers or toothpicks, with the feta on the bottom, so that they can stand flat. I used a channel knife to cut designs into the side of the cucumber before slicing it to make it prettier.
