Instructions

  1. Preheat Oven

    Set the oven to 425°F (220°C) and let it preheat while you prepare the ingredients.

    Time: PT5M

    Temperature: 425°F

  2. Slice Meats and Vegetables

    Trim any excess fat from the lamb and slice both the lamb and chicken breasts into long, uniform strips. Core and slice the red and green bell peppers and slice the onion into similar strips.

    Time: PT10M

  3. Make Seasoning and Toss

    In a large mixing bowl combine olive oil, apple cider vinegar, chili powder, cumin, smoked paprika, garlic powder, onion powder, salt, and black pepper. Add the sliced chicken, lamb, bell peppers, and onion. Toss everything together until the meat and veg are evenly coated.

    Time: PT5M

  4. Arrange on Sheet Pan

    Transfer the seasoned mixture onto a large sheet pan, spreading it out in a single, even layer so the pieces are not crowded.

    Time: PT2M

  5. Bake Fajita Mix

    Place the sheet pan in the preheated oven and bake for 20 minutes, stirring once halfway through to ensure even browning.

    Time: PT20M

    Temperature: 425°F

  6. Add Fresh Lime and Cilantro

    Remove the pan from the oven, drizzle the lime juice over the hot mixture, and sprinkle the chopped cilantro. Toss gently to combine.

    Time: PT2M

  7. Warm Tortillas

    While the fajita mix rests, warm the tortillas. You can heat them in a dry skillet for 30 seconds per side, or wrap them in foil and place in the oven for 5 minutes.

    Time: PT5M

  8. Serve

    Spoon the hot lamb‑chicken mixture onto each warm tortilla. Serve with optional rice and black beans on the side, or roll them up as tacos.

Critical Success Points

  • Preheat the oven to a high temperature (425°F) to achieve a quick char.
  • Spread the meat and vegetables in a single layer on the sheet pan; overcrowding will steam rather than sear.
  • Bake for the full 20 minutes, stirring halfway, until the edges are lightly caramelized.

Safety Warnings

  • Handle raw chicken and lamb with separate cutting boards and wash hands thoroughly.
  • Use oven mitts when removing the hot sheet pan.
  • Ensure the meat reaches an internal temperature of 165°F (74°C) for chicken.
