[thai] Neua Pad Prik (pepper Steak)

Cut the steak diagonally across the grain into thin strips (this may be easier if you chill the steak in the freezer first). Mix the marinade ingredients, combine with the steak, and leave for about an hour. In a wok or skillet over medium high heat, combine the sesame oil with two tablespoons of peanut oil and then stir fry the garlic and peppercorns until it is aromatic and the garlic turns slightly crisp. Add the beef, onions and sweet chilies, and stir fry for 2-3 minutes (until the beef begins to show signs of being cooked). Add the remaining ingredients, and increase the heat to high, and stir fry until the beef is cooked to your taste. Serve over steamed white rice and if desired garnish with a fried egg.
