>I'm interested in knowing if anyone has found a good substitute for cheese?

>soy-based "cheeses" that melt excellently, but they unfortunately all
>contain Casein (at least the name brands that I can find in my area).  Is my

>products such as vegan-rella that don't contain Casein but they don't melt
>and don't taste appropriate for a cheese substitute in dishes like Pizza.
>Any info/recipes anyone can share will be greatly appreciated!  Thanks...
