Ingredients

1/4 cup fresh basil leaves, plus 12 small leaves

1 large clove garlic

1 oz. finely grated Parmigiano-Reggiano (1 cup using a rasp grater)

1 15-oz. can navy beans, drained and rinsed

1/2 cup plain panko

1 large egg

Kosher salt

1 medium tomato, finely diced

8 Kalamata olives, pitted and chopped

2 Tbs. finely diced red onion

1 tsp. balsamic vinegar

2 Tbs. olive oil

4 whole-wheat hamburger buns, toasted

Preparation

In a food processor, pulse the 1/4 cup basil and the garlic until finely chopped. Add the Parmigiano, 1/2 cup of the beans, 1/4 cup of the panko, the egg, and 1/2 tsp. salt and process until smooth. Put the remaining beans in a large bowl and coarsely mash with a fork. Add the puréed bean and basil mixture and mix well.

Spread the remaining 1/4 cup of panko on a plate. With wet hands, form the bean mixture into four 3/4-inch-thick patties. Coat each patty with the panko, transfer to a plate, cover, and refrigerate for 10 minutes.

Meanwhile, in a small bowl, combine the tomato, olives, onion, balsamic vinegar, and the remaining 12 basil leaves. Set aside.

Heat a heavy-duty 12-inch skillet on high heat until very hot, about 1 minute. Add the oil and swirl to coat the bottom. Cook the burgers, flipping once, until browned, 5 to 8 minutes total. Serve the burgers on the buns, topped with the tomato-olive relish.
