| 1lb | Flank, round or shoulder steak |
| 2 tbsp | Olive oil |
| 8 oz | Fresh white mushrooms (about 3 cups), sliced |
| 3/4 cup | Diced onion |
| 1 cup | Mild salsa |
Preheat broiler. Season steak with salt and pepper to taste. Place on a broiler rack; broil about 4 inches from heat until desired doneness is reached, about 4 to 5 minutes on each side for medium-rare.
Meanwhile, in a large nonstick skillet heat oil over medium-high heat. Add mushrooms and onion; sauté until lightly browned and liquid evaporates, about 6 minutes. Stir in salsa, cook, mixing gently, until salsa is hot, about 15 seconds. Carve steak diagonally across the grain in thin slices and serve with Fresh Mushroom Salsa Sauce.
