This is a Martin Yan recipe....I watched him doing a demo of this at a Home Show years ago. Of course, he was showing off his amazingly quick chopping skills and the prep time, for him, was about 2 minutes. My prep time was longer, about 25 minutes! Get all your ingredients ready in little bowls, get your rice to cooking and when your rice is done, stir-fry the beef...dinner will be ready in 10 minutes once your ingredients are prepped. By the way, this is spicy....if you want it less spicy, use less dried red chilies. The dried red chilies, chili bean paste, hoisin sauce and dark soy sauce can be found in Asian markets or, increasingly, in major grocery stores in the Asian aisle.
