Oil grate on barbecue grill. Heat grill to medium to medium-high heat, approximately 375 degrees F.

In food processor, pulse cremini mushrooms until finely chopped. Scrape down sides occasionally. Transfer to large bowl.

In food processor, coarsely process black beans. (Note: Do not puree beans. Beans must be coarsely chopped.)

To bowl with mushrooms, add beans, onion and garlic. Using silicone spatula, mix together.

Mix in chili powder, cumin, oregano, salt and Worcestershire sauce. Season with pepper to taste.

Add bread crumbs and mix until well combined. (Note: If mixture is too wet, it won’t hold shape when attempting to form patty. If this occurs, add up to ½ cup more bread crumbs to mixture.)

Shape mixture into four patties about ¾-inch to 1-inch thick.

Transfer patties to grill; cook 6-8 minutes per side side or until crisp on outside.

Serve on buns with your favorite toppings and condiments.
