Drain and wash the beans. Add them along with all the other ingredients to a food processor and pulse / blend until it's smooth but with some good chunks still. You can also mash this mixture with a fork or potato masher in a large mixing bowl if you don't have a food processor. You can store the mixture in the fridge for 4 - 5 days. To make a taco, simply take out about 2 - 3 oz worth, and roll into a ball.
You can smash the taco in two ways. The first option is to add the bean ball to a heated and oiled, non-stick pan, then the tortilla on top, and then smash it.
The second option is to smash the ball into the tortilla. I recommend using some parchment or burger paper and a stiff spatula or burger press.
Then add that to a non-stick pan heated over medium with a bit of oil. I like to spray the smashed bean patty with oil too.
Pan fry until browned, about 3 - 4 minutes. You can flip and fry the tortilla for a few minutes as well if you like it to be a bit crispy.
Top with whatever you like! I've been doing my Cilantro Sauce or Chipotle Mayo, shredded lettuce and pico de gallo!
