To prepare Ancho Chile rub place all ingredients in a bowl and combine.
12-24 hours in advance rub steaks with Ancho Chile Rub. Place in refrigerator on an elevated rack over a baking sheet. This will dry brine the steaks, which gives them great flavor and will develop a beautiful crust when grilling.
Pull steaks from refrigerator 1 hour before grilling, allow to sit at room temperature.
Preheat grill to medium. Clean and season grates. Place the steaks on the heated grill and grill to desired doneness according to the Omaha Steaks Steak Cooking Chart. (For a Medium Rare steak about 8 minutes on the first side and 6-7 minutes on the second side.)
Remove steaks from grill. Let rest for 10-15 minutes. While steaks are resting rub peppers and onions slices with 2 T. olive oil, season with salt and pepper. Char peppers, jalapeno and onions on grill. Remove from grill, chop peppers, jalapeno and onions, place in serving bowl. Add remaining 2 T. olive oil, 2 T. red wine vinegar, cilantro and minced garlic. Season to taste with salt and pepper.
Serve steaks with grilled pepper and onion salsa.
