If you have a microwave oven, start by baking the potato for howe'ver long you usually do for a baked potato. Otherwise, you can boil it, or omit it. Chop onion and garlic finely. Soak tofu in a bit of soy sauce. Saute onion and garlic in saucepan until glossy, then add tofu. Saute until it looks like scrambled egg, then add the cooked, chopped potato, plus the green chile. Add the can of beans plus the spices (throw in whatever else you like) and heat it through. Serve wrapped in tortillas. This stuff is SUPPOSED to be hot!!
