Step 1

In a large bowl, combine the beans, onion, garlic, chipotles, adobo sauce, tamari, balsamic, cumin, salt, and pepper. Use a potato masher to mash until the mixture holds together but still has some visible chunks of black beans. Add the egg and use a spatula to fold until combined. Then, fold in the panko.

Step 2

Use your hands to form the mixture into 6 patties. The mixture should be cohesive and a little wet. If it’s too wet to handle, chill in the fridge for 20 minutes to firm up or mash your beans a little bit more.

Step 3

Heat a cast-iron skillet over medium heat. Brush with a little oil and cook the burgers for about 5 minutes per side, until charred on both sides, turning the heat down as necessary. The exact timing will depend on the heat of your stove and cookware.

Step 4

Alternatively, preheat an outdoor grill to 400°F. Lightly brush the patties with olive oil, spray the grill grates, and grill for 8 minutes on the first side and 4 minutes on the second side.

Step 5

Serve with hamburger buns and desired fixings.
