Veggie Burder recipes - Amy's-like?

Hi everyone.

I'm sure many of you are familiar w/ Amy's California Veggie Burger. It's by far my favorite veggie burger in the entire world!

That said, at $5 for four burgers, its not really that budget friendly and I don't get them that often. I'm wondering if anyone here has tried copying their ingredients list towards making their own version at home or if they know of a recipe that is similar, as as I really, really love those burgers and would love to be able to make a huge batch of them at home for a much friendlier price.

The recipe doesn't have to taste 100% like Amy's, but close would be good!

Thanks in advance for any help.
