A couple of high-protein, soy free vegan meat options.
Amy's breakfast patties taste a lot like smart bacon to me. They get a little gross and chewy around the edges if they're overcooked at all, but otherwise Amy's kitchen delivers. Check out the California burger on the same page, also soy free though I've never tried them.
Sunshine burgers are sunflower-seed based and have a very unique flavor. They're fatty, but the flavor is fairly light and appetizing. Doesn't taste quite like any other burger I've tried.
