Grilled Lamb Burgers

1 ¼ pounds ground lamb

1 egg

1 teaspoon dried oregano

1 teaspoon dry sherry

1 teaspoon white wine vinegar

½ teaspoon crushed red pepper flakes

4 cloves garlic, minced

½ cup chopped green onions

1 tablespoon chopped fresh mint, or to taste

2 tablespoons chopped fresh cilantro

2 tablespoons dry bread crumbs

⅛ teaspoon salt

¼ teaspoon ground black pepper

5 hamburger buns

Preheat an outdoor grill for medium-high heat, and lightly oil the grate.

Mix the lamb, egg, oregano, sherry, vinegar, red pepper flakes, garlic, green onions, mint, cilantro, bread crumbs, salt, and pepper together in a mixing bowl with your hands until evenly blended. Form into five patties.

Cook on the preheated grill until the burgers are cooked to your desired degree of doneness, about 4 minutes per side for medium-rare. An instant-read thermometer inserted into the center should read 160 degrees F (70 degrees C). Serve on buns.
