Ingredients

  • 1.5 lbs flank steak, thinly sliced
  • 2 red bell pepper, seeded, sliced
  • 2 green bell pepper, seeded, sliced
  • 1 large yellow onion, sliced
  • 3 tbsp olive oil
  • 1.5 tsp chili powder
  • 1 tsp ground cumin
  • 1 tsp smoked paprika
  • 1/2 tsp garlic powder
  • 1/2 tsp onion powder
  • 1 tsp kosher salt
  • 1/2 tsp black pepper, freshly ground
  • 2 lime, cut into wedges
  • 8 small flour or corn tortillas, warmed
  • 1/4 cup fresh cilantro, roughly chopped

Instructions

  1. 1

    Preheat oven to 425°F (220°C) and position a rack near the top. Line a large sheet pan with foil.

  2. 2

    In a small bowl, mix 1.5 tsp chili powder, 1 tsp ground cumin, 1 tsp smoked paprika, 1/2 tsp garlic powder, 1/2 tsp onion powder, 1 tsp kosher salt, and 1/2 tsp freshly ground black pepper to make the fajita seasoning.

  3. 3

    On the sheet pan, toss 2 seeded, sliced red bell pepper, 2 seeded, sliced green bell pepper, and 1 large sliced yellow onion with half the 3 tbsp olive oil and half the seasoning mixture.

  4. 4

    Toss 1.5 lbs thinly sliced flank steak in a bowl with the remaining olive oil and remaining seasoning. Spread the steak over the vegetables on the pan, keeping pieces in a single layer.

  5. 5

    Roast for 15-18 minutes until the steak reaches an internal temperature of at least 145°F (63°C) for medium-rare to medium and the peppers are slightly charred at the edges. For a char, switch to broil for the last 2-3 minutes.

  6. 6

    Squeeze half the 2 cut into wedges lime over the pan. Sprinkle with 1/4 cup roughly chopped fresh cilantro.

  7. 7

    Serve in 8 warmed small flour or corn tortillas with remaining lime wedges on the side.
