Ingredients:
- lbs Flank or Skirt Steak, trimmed of excess fat
- tablespoons Olive Oil
- tablespoons Freshly Squeezed Lime Juice
- tablespoon Chili Powder
- teaspoon Ground Cumin
- teaspoon Smoked Paprika
- teaspoon Garlic Powder
- ½ teaspoon Dried Oregano
- teaspoon Kosher Salt, plus more for finishing
- ½ teaspoon Freshly ground Black Pepper
- Bell Peppers (1 Red, 1 Yellow, 1 Green), sliced thinly
- large Yellow Onion, halved and sliced thinly
- tablespoons Vegetable Oil (High smoke point), divided
- medium Flour Tortillas
Instructions:
- Slice the steak thinly against the grain into uniform strips.
- In a small bowl, combine chili powder, cumin, paprika, garlic powder, oregano, salt, and pepper to create the spice rub.
- Toss the sliced steak strips with the olive oil, lime juice, and the entire spice rub mixture. Set aside briefly while preparing vegetables.
- Slice the peppers and onions uniformly.
- Heat half the vegetable oil in a large, heavy-bottomed cast-iron skillet over high heat until shimmering. Add half the steak mixture, spreading it into a single layer. Sear quickly (1-2 minutes per side) until nicely browned. Remove immediately to a clean plate. Repeat with remaining oil and steak.
- Add the remaining oil (if needed) to the same hot pan. Add the sliced onions and peppers. Sauté vigorously, stirring often, for 4–6 minutes until tender-crisp and slightly charred.
- Return the cooked steak (and any accumulated juices) back into the pan with the vegetables. Toss quickly for 30 seconds just to heat through. Taste and adjust seasoning.
- Warm the tortillas just before serving according to package directions.
- Serve the sizzling steak and vegetable mixture immediately with the warm tortillas and desired toppings.
