Awesome :) I think I've tried "Go Veggie!" and "Daiya" brands from the super market. If you melt the Go Veggie brand into vegetable chili and then put that on top of some baked pita chips, you are in for an enjoyable meal ^.^
Just FYI, Go Veggie isn't vegan or dairy free (at least last time I checked), it's lactose free.
Also, Daiya isn't the state of the art by a long shot. If you're adventurous and have a large grocery budget, Chao (served cold) is the most cheese-like cheeze that I've had so far.
That said, there have been improvements and more awesome brands appearing every year! Check out miyoko’s cheeses and butter!
