The black bean patties I've tried so far were all good, but I am on the hunt for GREAT. I am closer. Last night I added a cup of cooked quinoa to a small can of black beans (drained and rinsed) and mashed. Then I added a tbsp. of GF Worchestershire sauce, salt and pepper, MCCORMICS garlic and onion powder, a handful of Daiya cheese shreds, 1 grated carrot, about a half cup of sauteed, chopped mushrooms, and 2 tbsp. of ground chia. It still seemed just a little mushy, so I added 1 tbsp. of rice bread crumbs as well. The consistency was just right, so I fried up some patties and some meatballs in garlic olive oil. Yum. I served us each a patty, with homemade red/purple potato salad and creamy coleslaw (both made with veganaisse). It was so good, I had some leftovers for breakfast this morning. :)
This meal was vegan and gluten-free; also free of nightshades. There are other black bean patty recipes below. It's been fun to experiment and you can't really "fail," only create patties that you may like either more or less than the last one. So start with a small can of black beans, drain and rinse them, then experiment with the ingredients and seasonings you like best. I suggested McCormick seasonings because they are gluten-free... at least, it would seem. Other seasonings often contain fillers or "natural" flavours that are made with gluten. If you are gluten-free, please make sure your seasonings and flavourings are as well. (Vanilla extract for instance, is often made in grain alcohol. That's grain, as in gluten.)
Also try to add some Omega-3 ingredients, such as Chia and/or freshly ground flax seeds. You can even add protein powder if you can have it. It will help absorb the moisture of the black beans, and add protein to your vege patty as well.
Have fun, and enjoy!!
