Heat oil in a large nonstick skillet over medium-high heat. Add shallots; sauté 3 minutes or until lightly browned. Add thyme, 1/8 teaspoon salt, crushed red pepper, and mushrooms; sauté 6 minutes or until lightly browned. Add garlic; sauté 2 minutes. Stir in wine and soy sauce; cook 15 seconds or until liquid almost evaporates. Stir in parsley; cover and set aside.
Heat a grill pan over medium-high heat. Coat pan with cooking spray. Sprinkle steaks with 1/2 teaspoon salt and black pepper. Add steaks to pan; cook 3 minutes on each side or until desired degree of doneness. Let stand 5 minutes. Serve with mushroom mixture.
Wine note: To contrast the leanness of grass-fed beef, serve it with a full-bodied, soft red. Many varietals would work, but cabernet sauvignon's structure and depth have a special affinity with beef. Try the Geyser Peak Cabernet Sauvignon 2005 from the Alexander Valley of California.
