Black Bean and Mushroom Burger

Prepare a medium-hot fire in the grill with a lightly-oiled vegetable grill rack in place.

Heat the oil in a large skillet over medium-high heat. Add the onion and cook, stirring, until golden, about 4 minutes. Add the mushrooms, garlic, and cumin and cook, stirring, until the mushrooms have released their juices, about 5 minutes.

Spoon the mixture into the food processor. Add the beans and cilantro and process briefly until well combined but still chunky. Spoon into a bowl, stir in the goat cheese, if using, and bread crumbs. Season generously with salt and pepper.

With wet hands, form the mixture into burgers. Mist both sides with nonstick spray. Grill the burgers until crisp and heated through, about 5 minutes per side.

Serve the burgers on the buns, passing salsa at the table.
