'The Taiwan Burger' Made of Cool Whip
The burger genre has been pretty flexible, lending its name out to portobello mushrooms, chicken, tofu, and seitan, but it needs to draw the line at non-dairy white fluff. Diana of An Appetite for China spotted this "Taiwan burger" made of a Cool Whip "patty" and lettuce at a Buddhist vegetarian restaurant in Beijing. Cool Whip sandwich might arguably be a better name for it, or even better, this argument should really not exist at all.
