Mini Hamburgers?

Here is what my son and a freind made a few days ago - mini "hamburgers". I've seen these several places on the web and I had the items on hand.

They are made from:
vanilla wafers (like Nilla Wafers) for the bun
fruit roll ups yellow and red for the tomato and cheese
mint patty (like York Peppermint pattie) for the burger
coconut with green food coloring for the lettuce
real sesame seeds
a small amount of caramel sauce on top of the bun so the seeds stick
