Chef’s Note: If you’re not a lamb fan, you can easily replace it with ground beef.
In a large bowl, add the ground lamb meat, shiitake mushrooms, garlic, ginger, red onion, cilantro, oyster sauce, Sriracha and mix well. Form into 4 patties and place onto baking sheet. Spray both sides of burgers with non-stick cooking spray. Grill over high heat 2 to 3 minutes per side or to desired temperature.
To assemble, add burgers to buns and serve with your favorite toppings and condiments.
