• 2 Tbsp Fresh Cilantro (chopped)
• 1 Green Onion (thinly sliced)
• 1 Garlic Clove (minced)
• 0.5 cup Full‑Fat Greek Yogurt

Instructions

1. Preheat Oven and Sheet Pan

   Place a rimmed sheet pan in the oven and preheat to 450°F (232°C) so the pan gets hot before adding the ingredients.

   Time: PT10M

   Temperature: 450°F

2. Prepare Vegetables and Chicken

   Thinly slice the bell peppers, onion, and chicken thighs. Thin slices cook faster and absorb the marinade better.

   Time: PT15M

3. Make the Quick Marinade

   In a small bowl whisk together olive oil, honey, lime juice, soy sauce, garlic powder, chili powder, oregano, salt, and pepper.

   Time: PT5M

4. Combine Ingredients

   In the large mixing bowl, combine the sliced chicken, peppers, and onion. Pour the marinade over everything and toss until evenly coated.

   Time: PT5M

5. First Roast

   Transfer the coated mixture onto the pre‑heated sheet pan in a single layer, avoiding overcrowding. Roast for 15 minutes, stirring halfway through.

   Time: PT15M

   Temperature: 450°F

6. Prepare Yogurt‑Cilantro Sauce

   While the fajitas roast, blend cilantro, green onion, garlic, Greek yogurt, lime juice, salt, pepper, and optional jalapeño or sriracha until smooth.

   Time: PT5M

7. Drain and Reduce Pan Liquids

   After the first 15 minutes, remove the pan. Carefully pour off excess liquid into a saucepan, leaving a thin layer on the vegetables. Return the pan to the oven for another 15 minutes.

   Time: PT15M

   Temperature: 450°F

8. Reduce the Collected Liquid

   Place the saucepan with the drained liquid over medium heat and simmer for 5 minutes, stirring occasionally, until it thickens slightly.

   Time: PT5M

   Temperature: Medium heat

9. Warm the Tortillas

   Spray a skillet with coconut oil spray, heat over medium‑high, and warm each corn tortilla for about 30 seconds per side. Stack them under a clean kitchen towel to keep warm.

   Time: PT5M

   Temperature: Medium‑high

10. Finish and Serve

    Remove the fajita pan from the oven, drizzle the reduced pan sauce over the chicken and vegetables, then plate. Top with avocado slices, a dollop of the yogurt‑cilantro sauce, and optional hot sauce. Serve with warm corn tortillas.

    Time: PT5M
