Salisbury steak is a classic for a reason. Rich beef flavor, both from actual beef and beef soup mix, entice everyone to gather around the table. Keep it classic by serving with potatoes cooked up any way you like 'em.
In a large bowl combine beef, 2 tablespoons of the soup mix, and 1 tablespoon Worcestershire sauce; mix well. Shape in 4 oval patties about 1/2-inch-thick.
In a large skillet cook patties in hot oil over medium-high heat 4 minutes or until browned, turning once. Remove; set aside. In hot skillet cook garlic in butter over medium 30 seconds. Add mushrooms. Cook and stir 5 minutes or until tender. Add water, wine, tomato paste, and remaining Worcestershire sauce and soup mix. Stir, scraping up browned bits. Return patties to skillet; spoon sauce over. Cover; cook over medium-low heat 8 to 10 minutes or until patties are 160°F. Serve with mashed potatoes and garnish with chopped parsley and/or thyme, if desired.
