Ingredients
  

Fajita Ingredients
  • 1.5 lbs Chicken Breast 680g, sliced into thin strips
  • 3 large Bell Peppers Red, green, and yellow, sliced into strips
  • 1 large Red Onion 200g, thinly sliced
  • 3 tbsp Avocado Oil 45ml
  • 1 tbsp Chili Powder 15g
  • 2 tsp Smoked Paprika 10g
  • 1 tsp Cumin 5g
  • 1 tsp Garlic Powder 5g
  • 1/2 cup Fresh Cilantro For garnish
  • 2 whole Limes Cut into bright green wedges

Equipment

  • 1 Large metallic baking sheet
  • 1 Large Mixing Bowl

Method
 

Prepare the Oven and Sheet Pan
  1. Preheat your oven to 425°F (220°C). Position a rack in the center of the oven.
  2. In a large bowl, toss sliced chicken, peppers, and onions with oil and roasted fajita seasoning until heavily coated with an oily sheen.
Roasting Process
  1. Spread the mixture onto a metallic baking sheet in a single layer, ensuring ingredients are not overcrowded.
  2. Roast for 18-22 minutes. At the halfway point, toss with a spatula to ensure the chicken develops golden-brown charred edges and the onions become translucent.
Finishing Touches
  1. Remove from the oven. Scatter fresh green cilantro leaves over the pan and arrange bright green lime wedges around the edges.

Notes

Use two pans if your vegetables look crowded to ensure they blister rather than steam.
For extra char, broil on high for the final 2 minutes of cooking.
