Preheat the oven to 325 degrees.
Drain and rinse the black beans. Pat dry. Don't stress about getting them completely dry, just fairly dry.
Spread the beans on a parchment-lined baking sheet. Place in the oven and bake for about 15 minutes until the beans are split and dried out.
While they are drying out, start your veggies. Heat a small saute pan over medium heat. Add olive oil and heat. Add onions, peppers, and whatever other veggies you are using. Saute for about 5 minutes and add the minced garlic. Continue to cook for another 2-3 minutes.
By now, your beans should be just about done. Pull them from the oven, then turn the oven up to 375 degrees, if you are baking. If not, check the other instructions below. Allow the veggies and beans to cool a few minutes before moving on.
Next, add the veggies to a food processor. Pulse once or twice, just to break them up a little more.
To them add the flour and pulse once or twice. This will help to continue to cool down the veggies. Add remaining ingredients and pulse several times until it is mixed up. Be careful not to overmix. You still want chunks of beans, so don't mix too much.
Next, I used a scoop to get the same-sized burger. So scoop, then flatten slightly on the baking sheet. Bake for about 5 minutes, then flip the burgers and bake for 5 minutes on the other side.
If you prefer other cooking options here are 2 I like:Cooking in a skillet or electric griddle. Heat pan or griddle over medium-high heat. Coat lightly with the oil of choice. Once the pan is good and hot, add burgers. Cook for about 3 minutes per side. Cooking on the grill is a little more tricky. Form your burgers and freeze for about 5 minutes while the grill is heating. Heat grill on high. Grease grates and add burgers. Cook for 2-3 minutes per side. Serve immediately.
