Add the beans, flax egg, hot pepper, garlic, onion, parsley, ginger, cumin, oregano, and chipotle powder to the food processor. Mix until the beans are well incorporated, but leave some whole beans in there. It should be chunky, not a smooth paste.
Pour the mixture out into a large bowl and add in the steamed sweet potatoes or the purée, and the cauliflower crumbs for binding. Mix well.
Cover the mixture and refrigerate for 20 minutes
Remove from the fridge and divide the mixture into 8 equal portions. Shape into patties.
You can then cook them in a skillet with a spray of avocado oil until golden brown.
If you are choosing to be oil free, place the shaped patties on a parchment covered baking tray and bake for 12 minutes at 430 F until golden brown, and then flip and bake for another 5-8 minutes.
