Squeeze a thick, wavy line of green icing all along the rim of the flat side of one Nilla wafer.

Press the fudge cookie into the green frosting. Press hard enough so some green starts to poke out over the edge, resembling lettuce.

Squeeze yellow and red frosting on top of the fudge covered cookie. Alternate patterns so that some red and yellow are visible along the outer edge of the cookie.

Cover with another Nilla wafer.

Place about 1/4 Cup water into a small bowl. Dip your finger into the water then on to the top of the covering Nilla wafer in the completed burger cookie.

Dry your finger off and then press it into some sesame seeds. Press the sesame seeds into the wet spot on the Nilla wafer.

Continue process until all cookies are completed.

Store at room temperature in a covered container for up to a week.
