Place tofu in a bowl and mash with a potato masher.
Add mayonnaise, if desired, mustard, soy sauce and
tumeric. Mix well until tofu takes on a bright yellow
color. Stir in scallion, celery and relish, if desire.
Serve as a spread on bread or stuffed into pita bread.
NOTE: Weight Watchers makes a mayonnaise that is
fat-free -- no oil, no eggs.
