Off topic, here, but I have to give you other herbivores a good recipe if you're craving a cheeseburger...

Slice a block of extra firm tofu in to 1/2 inch patties and put them between some paper towels. Put a cookie sheet on top of them and weigh it down with something heavy (I use a couple of bottles of wine). After 30 minutes, put them in a zipper bag with some worchestershire sauce and let them marinate for as long as you can stand it (at least 30 minutes, but longer is better). Throw them in a lightly oiled, hot pan, and cook them for a few minutes on each side. Season with Hamburger seasoning and pepper, then throw a slice of cheese or cheese subsititute of your choice on top. Toast a whole wheat bun while they cook. Put your favorite condiments & burger toppings on, then put the cooked tofu in and VIOLA! Tofu burger!
