The flavor of this veggie burger was great. I wasn't sure what toppings to use, but we ended up deciding on tzakiki, cucumber, and feta, served in a whole wheat pita. I think that was a good choice, though I'd love to hear other ideas.
My main problem with these burgers was that they crumbled as soon as we bit into them -- it seemed like they might have needed some more moisture to hold them together, although they were nice and crunchy so I wouldn't want to change that. With the remaining burgers I think I might crumble them onto a pizza like sausage -- again with the combination of cucumbers, feta, and tzakiki like I used previously.
