  1. Place steak in glass baking dish and coat evenly with salt and pepper. Mix together remaining marinade ingredients and pour over steak. Marinate for a minimum of 30 minutes on each side or overnight, flipping steak at least once.
  2. While steak is marinating, prepare topping. In a sauté pan, heat olive oil and sauté shallots for 5 minutes, or until they begin to soften.
  3. Add mushrooms, sundried tomatoes, and salt and pepper to taste. Cook until mushrooms become tender, about 5 minutes.
  4. Add spinach and stir until wilted. Remove from heat, keep warm.
  5. Place rack in middle of oven and preheat broiler on high for at least 5 minutes. Place meat in oven and broil for 15 minutes; turn over and broil an additional 10 minutes. Check temperature and continue broiling until internal temperature reaches 160°F.
  6. When steak is done, remove from oven and allow to rest for 5 minutes. Cut steak into 1/2-inch slices and top with vegetable mixture. Serve immediately.
