This is one of the most satisfying tofu patties I have ever tasted!
The preparation was not hard, it was more of a getting everything you need for making the patties ready. Also the patties did not bind well, so I had to put in whole wheat flour to make the patties stick together while frying.
I improvised on the burger, I used sour dough bread, tofu patty, homemade kimchi, avocado, and mustard in my burger. YUM!
This recipe also seemed to be a favorite among other vegan bloggers, but some of them also had trouble getting the patty to stick well, so you may have to watch out for it:
