Here's what I made on the 4th of July this year. Of course I found it on Pinterest and it was a modification of this one I made earlier in the year.
How to make:
Vanilla wafers for the buns
Red,Yellow, & Green Food Coloring
Get two vanilla wafers. Insert grasshopper cookie for the meat of the burger. Tint coconut green in a baggie for your lettuce. Tint frosting. Some red (for the ketchup), some yellow (for the cheese). Add a little cheese and ketchup (your frosting) and then roll in the coconut for the lettuce. Brush some sugar water on the top of the hamburger and sprinkle on your sesame seeds. Voila. Your done. Easy as pie....or easy as hamburgers.
