Grind the tofu, potato and onion (if using) in a food processor. Don't let it get too fine. Mix in remaining ingredients, shape into burgers and bake at around 350 degrees on a very lightly oiled cookie sheet for 15-20 minutes, turning once. They can also be fried. This recipe was the Judge's Choice award winner in the "Build a Better Burger Contest" sponsored by the North American Vegetarian Society.
