Maitake Mushroom Burger

1. In a large bowl, mix together the ground beef, salt and pepper. Divide the ground beef mixture into 4 equal parts and shape them into patties, about 1-inch thick.

2. Prepare a charcoal or gas grill fire. Grill the burger patties for 6-8 minutes total, or until desired level of doneness. Alternatively, you can cook the burgers in a frying pan on medium-high heat, 8-10 minutes total.

3. In the meantime, heat a frying pan with the butter over medium-high heat. When the butter starts bubbling, add the garlic and the mushrooms and saute for 2 1/2 minutes, or until the mushrooms have softened. Add in the soy sauce and the Worcestershire sauce and continue to cook for another 1 minute.

4. Assemble the burgers on the buns with cheese, and top with the sauteed mushrooms.
