2 tablespoons butter
1 teaspoon Worcestershire sauce
1/4 teaspoon lemon juice
1 garlic clove, crushed
1 onion, sliced
1 cup sliced mushrooms
1 pound lean ground beef
1/2 teaspoon salt
1/4 teaspoon pepper
Melt butter in a large skillet. Add Worcestershire sauce, lemon juice, crushed garlic clove, sliced onion, and sliced mushrooms. Cook and stir over medium heat for 2 minutes; remove from the heat.
Mix together ground beef, salt, and pepper. Shape into patties, each about 3/4-inch thick.
Push the mushroom/onion mixture to the side of the skillet and cook the patties over medium-high heat, turning once, until done, about 10 minutes.
