In 2 separate bowls, place  2-3 Tablespoons of white frosting in each. In the first bowl, place 1 drop of red food coloring and 1 drop of yellow coloring in the frosting and stir. Play with colors 1 drop at a time until the mixture looks the color of yellow American cheese. In the second bowl of frosting, place 1-2 drops of green coloring and stir. Play with color until the mixture looks the color of lettuce. 

Place 1 Tablespoon of honey in a small dish.

Take two vanilla wafer cookies and 1 chocolate cookie. On the flat side of the vanilla wafer spread about 1/8 of a tsp of orange frosting. On the second vanilla wafer (flat side) spread about 1/8 tsp of green frosting. 

Place chocolate cookie (hamburger patty) between the two frosted cookies and squeeze together gently- just until frosting oozes out the sides. You may need a little more frosting- after making a few you will get the hang of how much you will need.

Dip a toothpick in honey and “paint” a small amount on top of the cookie (the “bun”). Sprinkle sesame seeds on top of honey (this helps the seeds to stick to the bun).

Repeat with remaining cookies and frosting.
