Here's the recipe (I only provide measurements for tofu and soy milk, the rest is really up to your tastes):
1 12 oz package silken style tofu (I used mori-nu firm silken)
2 cups soy milk
Soy or rice parmesan
pepper & salt
pre-made crust or from scratch (there's a kroger brand one that has no dairy products in it, and is cheap)
To make the alfredo, mash up the tofu and the soy milk. I did this by hand, and it worked out OK but it did take a fair amount of time. It'd be considerably easier with a food processor or blender.
Put mixture in pot over medium-low heat. Stir in parmesan and spices. The parmesan is what adds thickness, so add to taste/firm. I also added a little tofutti cream cheese, I figured it wouldn't hurt anything ;-)
Once the alfredo is done, cut up those veggies, and throw it all together. We added (if I recall) the sauce first, then onions, mushrooms, spinach, and tomatoes. I also sprinkled a little parmesan on top for good measure. Cook at 450 degrees for 10-12 minutes (or until the crust is brown).
