Combine ground beef, oil, garlic, salt and 1/4 teaspoon seasoned pepper. Mix well. Shape into 4 patties. Wrap each patty with bacon, as you would a fillet mignon steak, and fasten with toothpicks. Cook on grill 10 to 15 minutes on each side or to desired doneness, or cook on broiler. In a skillet, saut� mushrooms in melted butter; add Worcestershire sauce, hot pepper sauce, and 1/4 teaspoon seasoned pepper. Serve with the mushroom sauce.
