Prepare a baking sheet with a sheet of parchment paper. Set aside.
Place all of the ingredients into the food processor. Pulse until well-combined and the ingredients hold together well. *No food processor? First mash the beans in a bowl until smooth; then fold in the remaining ingredients until well-combined.
Wet your hands to prevent sticking. Pour the combined mixture onto a baking sheet or cutting board, forming into a rough square shape. Use the side of your hand to "cut" into 4 equal square portions. Form each portion (wet hands again if the mixture is sticking) into a round burger shape about 1" thick, then place on the parchment paper; repeat with the remaining burgers.
Refrigerate the burgers for 30 minutes. Meanwhile, preheat the oven to 400 degrees.
After the burgers have rested in the refrigerator for 30 minutes, place the burgers (still on the parchment paper on the baking sheet) into the oven.
Cook for 15 minutes, carefully flip the burgers, then bake for another 15 minutes until golden brown and slightly crunchy (yum)!
*If you prefer to pan-saute these burgers in a skillet, preheat a skillet over medium heat, add about 1 tb of oil, then cook the burgers for 8 minutes per side.
Serve with your favorite burger toppings and enjoy!
