1 pound boneless sirloin steak (about 1/2 inch thick)
1/4 teaspoon salt
1/4 teaspoon black pepper
How to Make It
Combine sherry and next 5 ingredients in a small bowl; set aside.
Sprinkle both sides of steak with salt and black pepper.
Place a large nonstick skillet over high heat; add steak, and cook 3 minutes. Reduce heat to medium-high; turn steak, and cook 3 minutes or until desired degree of doneness. Remove steak, and set aside.
Add sherry mixture, scraping bottom and sides of pan to loosen browned bits; cook over medium heat 1 minute, stirring constantly. Slice steak, and serve with sauce.
