1. The night before or morning of pierce the steak an inch apart all over with a fork on both sides; season lightly with salt and pepper. In a small bowl whisk lime, oil, garlic, jalapeno, chile powder, cumin and oregano together. Season lightly with salt and pepper. Pour over steak in a shallow dish or pan or put the steak in a large Ziploc bag and pour the marinade over. Marinate at least 6 hours or longer in refrigerator.
2. Heat 2-3 tablespoons oil in a large skillet and add peppers and onions, season lightly with salt and pepper and cook over medium-low heat until desired tenderness. Remove to a small platter or dish.
3. Remove the steak from the marinade, wipe off the garlic and pat dry. Heat the skillet over high heat and cook the steak 3-4 minutes on each side depending on how well done you prefer it. You can also grill it if you prefer. Remove to a cutting board and allow to sit for at least 5 (to 10) minutes. Slice into thin strips against the grain at an angle.
4. Serve immediately on warm tortillas with peppers, cilantro, lime and your choice of toppings.
