Ingredients
  

Main Ingredients
  • 1.5 lbs Steak (flank, skirt, or sirloin)
  • 3 Bell peppers (red, green, yellow) sliced
  • 1 Onion (large) sliced
  • 2 tbsp Olive oil
  • 2 tbsp Fajita seasoning
  • 1 Lime for juice
  • 12 Tortillas (flour or corn) small
  • Salt & pepper to taste
Optional Toppings
  • Sour cream
  • Salsa
  • Guacamole
  • Shredded cheese

Equipment

  • Cutting board
  • Sharp knife
  • Large mixing bowl
  • Large skillet or cast-iron pan
  • Tongs or spatula

Method
 

Preparation
  1. Thinly slice the steak against the grain to ensure tenderness.
  2. In a bowl, combine the sliced steak with 1 tablespoon of olive oil and fajita seasoning; allow it to marinate for at least 15 minutes.
  3. Slice the bell peppers and onion into thin, uniform strips.
Cooking
  1. Heat the remaining 1 tablespoon of olive oil in a large skillet or cast-iron pan over medium-high heat until shimmering.
  2. Add the marinated steak to the hot skillet and cook for 2-3 minutes per side until seared and cooked to your desired doneness, then remove and set aside.
  3. Add the sliced bell peppers and onions to the same skillet, cooking for 5-7 minutes, stirring occasionally, until they are tender-crisp.
  4. Return the cooked steak to the skillet with the vegetables, squeeze fresh lime juice over everything, and toss to combine.
Serving
  1. Warm the tortillas according to their package directions.
  2. Serve the steak fajitas immediately with the warm tortillas and your preferred toppings.

Notes

For extra flavor, marinate the steak for at least 30 minutes, or even up to 4 hours in the refrigerator. Ensure your skillet is very hot to get a good sear on the steak and vegetables.
