I think this is crazy, but here's a start.
1 block soft tofu, drained
1/2 c. soy milk
1/2 c. sugar
1 T. vanilla, lemon, or almond (which ever you prefer)
1/4 c. maple syrup
1 gram cracker crust
blend up the stuff, pour into the crust, bake 350 for 30. chill. Top with blueberries (or whatever) Kebler reduced fat gram cracker crust is apparently vegan.
