Ingredients
1 can (15 ounces) kidney beans, drained and rinsed
1 shallot, minced
1 carrot, finely grated
3 cups cooked quinoa
2 tablespoons chopped fresh parsley
3 tablespoons crumbled feta
1 teaspoon coarse salt
2 egg whites, lightly whisked
2 tablespoons extra-virgin olive oil
6 whole-wheat buns, grilled
Whole-grain mustard, for serving
Grilled onions, for serving
Radicchio, for serving
Preparation
In a bowl, mash beans into a thick paste and mix in shallot, carrot, quinoa, parsley, feta, salt, and egg whites.
Form mixture into six patties and chill 30 minutes.
Heat 1 tablespoon oil in a skillet over medium-high heat, directly on grill grates or on stove top, and cook patties until golden (add remaining tablespoon oil if cooking in batches), 4 to 5 minutes per side.
Serve on buns with mustard, grilled onions, and radicchio.
