The green will look really vibrant at first, but it will gradually mute down as the buns dry.
Using a shot glass or a small bottle cap, punch holes into the slices of cheese to make small circles. This is for the mushroom spots on top of the buns. Each slice yields about 5 small circles.
After coloring the buns, place it on grill (color face up) to toast and give it some heat. Remove from grill after a light toast. Place the cheese circles onto the colored surface to resemble the mushroom spots. The warmth of the bread will make the cheese stick.
