1 lb. Bag frozen, cut string beans (thawed; will only use partial bag)
Various vegetables to decorate (we used chives, diced carrots, peas, celery)
In a medium mixing bowl, add yellow food coloring to the potatoes and stir to combine; add a few drops of red food coloring to the potatoes and stir again to mix the colors, adding more red coloring to achieve the desired shade of orange.
Using clean, damp hands, form the potatoes into 32 small balls (each about 1 1/2-inches in diameter). On each of 4 microwave-safe plates, arrange 8 potato balls, side-by-side and overlapping each other slightly, to form curved caterpillar bodies. Insert green beans for legs on the sides of the caterpillar bodies.
To finish, decorate each caterpillar with additional vegetables of your choice. To achieve our look, make stripes down the back of the bodies with thawed frozen carrot cubes, chives snipped to 1/2-inch lengths, thawed frozen peas for eyes and a slice of celery for a smile. Reheat the caterpillars in the microwave and serve.
