10 oz tofu (extra firm)
 3 tsp vanilla extract
 2 Tbsp maple syrup (or other sweetener) or to taste
 1/2 cup tahini (sesame butter)
 3/4 cup cold water or soy milk
 1/4 cup walnuts (chopped med. coarse)
 3 Tbsp cocoa powder
 prepared and cooled 9 inch pie crust of your choice
 Cube tofu and process in food processor until very smooth.  Add
 vanilla and maple syrup while continuing to blend.  Stop and add
 tahini, then continue to blend (mixture will clump up but smooth out
 with continued processing).  Add liquid in two or more additions,
 blending between.  Mixture should be quite soft and probably has
 become quite warm.  Divide mixture in half; leave one half in
 processor.  Fold walnuts into the 1/2 mixture in bowl and cocoa powder
 into the 1/2 mixture in the processor.  Blend tofu and cocoa mixture
 till smooth.  Spread the two mixtures into a prepared and cooled pie
 crust of your choice.  Now, swirl the vanilla and chocolate layers
 together for an attractive appearance.  Chill thoroughly and serve
 with whipped cream or rice dream (available at health food store)
