Preheat oven to 325°F. Spread beans evenly onto a lined baking sheet. Place in the oven and bake for 15 minutes until the beans have dried out.
Meanwhile,in a large skillet set over medium heat, add olive oil. Sauté onion and garlic until soft, about 3-4 minutes.
Add to the bowl of a food processor along with the remaining ingredients (with the exception of the beans). Pulse everything together for 30 seconds, then add the black beans. Pulse the mixture, leaving larger chunks of beans.
Remove the mixture from the food processor 1/3 cup at a time and form into patties (don’t form them too thick).
Place the large skillet back on the heat, add extra oil if necessary. Cook patties on each side for 4-5 minutes or until golden brown. Serve immediately, garnish with desired toppings.
