Substitute meat burgers vary widely in quality. I used to make the classic Natureburger by hand from the box mix--I was terrible at it because I'd get the patties too thin, and they'd fall apart while I was frying them. Then they came out with all the frozen variants: Boca, MorningStar, Gardenburger(ADM), Amy's and Dr. Praegers (and various trader joe's house brands which I will admit, I used to make in the toaster.) But Erewhon deli makes their own--tofu mixed with fresh(?) carrots, celery and onion in small but recognizable chunks, with a little parsley thrown in. It's been lightly deep fried to give it that all-over golden color, but it's not greasy. And it's damn good. Truly the tastiest non-meat burger I've had. It's a thick patty, but it's fairly soft and easy to chew, not like those frozen patties that turn into dried mealy disks or squishy tepid mush (when thawed but not dried by cooking.) Sometimes I get the whole sandwich, but usually I just buy the patties so I can put my own random assorted condiments on it at home.
