Step 1: Mix Worcestershire sauce and mustard. Place steak strips in the mixture. Cover, and marinate in the refrigerator at least 30 minutes or overnight for maximum flavor.
Step 2: Heat olive oil in a medium saute pan over medium heat. Stir in the onion and garlic, and cook until tender. Season with pepper. Place steak into the saute pan and cook about 5 minutes, or to desired doneness.
