1Heat the oil in a large skillet over medium-high heat. Add the onion and sauté for 4 minutes. Add the brown sugar and stir until melted. Add the tomato sauce, garlic powder, pepper, Worcestershire sauce, red pepper sauce, chiles, and chili powder, stir, and heat through. Remove from the heat and set aside.
1heat the coals to medium-hot. Pour half the sauce into a bowl and get a basting brush. Allow the lamb to sit at room temperature for 30 minutes prior to grilling.
2Grill the lamb steaks four inches from the coals for 7 to 10 minutes per side or to desired degree of doneness: 145ºF for medium-rare, 160°F for medium or 170°F for well. Baste the steaks frequently with the sauce during the last 7 minutes of cooking.
3Remove the steaks and serve with the remaining barbeque sauce.
