Prepare the grill if you are grilling the tofu, and grill it on
both sides, about 6 inches above the coals, until it is well-browned
and a little crispy. Otherwise, broil the tofu on both sides. Spread
the bread with mayonnaise and horseradish to taste.
Slice the tofu
in half, crosswise, to make pieces 1/2-inch thick, and cut the pieces
to fit the bread. Arrange the tomato slices on the tofu, and salt
and pepper them; add the onion if desired. Cover with the lettuce
and another slice of bread.
Yield: 2 sandwiches
Be sure to use the firm, Chinese-style tofu rather than the soft
or regular tofu. It tastes best after it has been marinated for
