Quoting Mary.:" This is going to be so very very hard for me. Im not sure if i can even do it Im so picky with my food ... [snip!] ... of some animal derived item... The list of food i will not try and hate is to infinity and beyond. is this possible for me?"
Look for Almond cheese or Cashew chese. Almond seems a little more rubbery, but I have found some decent cashew cheeses around town. I do use soy sour cream (tofutti or something like that) but I will warn you it tastes NASTY unless you mix it with other spices or foods. I like to make a black bean dip with the sour cream and some salsa. Doesn't taste too terrible. :-)
I like almond products WAY more than soy products.
Also, I've become addicted to humus since going vegan.
I had to switch to non-dairy a few months ago, it hasn't been so bad but it took some research to actually find foods that don't suck. Good luck. If it's any consolation, I lost almost all of my baby weight after switching to non-dairy.
