Step 1

Preheat the oven to it's lowest temperate and place a large baking tray in there to warm. Then cut the peppers and onion into slices.

Step 2

Place the chicken on a plate, pour on 2 tbsp of the oil and sprinkle on the fajita seasoning. Mix together until thoroughly combined.

Step 3

Heat a cast-iron griddle plate to a high heat, when hot, place the tortillas on the griddle - turning once until you have griddle lines on the tortillas. It should only take a minute or two, but you'll probably need to do this in 2 or 3 batches. Place on a plate and cover with some foil to keep warm.

Step 4

Brush the griddle with the remaining 1 tbsp of oil. Place the sliced peppers and onions on the griddle and fry until slightly charred and softened (about 8-10 minutes), turning once or twice during cooking. Remove and place on the warmed baking tray (take the tray out of the oven now so it's not too hot to serve).

Step 5

Place the chicken on the hot griddle and cook until charred and no longer pink in the middle (about 5-6 minutes). Turn over once during cooking.

Step 6

Place the chicken on the tray along with the warmed tortillas, avocado slices and coriander/cilantro. Serve with the sour cream, salsa, shredded cheese, jalapenos and lime wedges.
