Place Marinade ingredients in a large bowl and mix. Add chicken, toss well to coat. Marinade for 1 hour to 24 hours (or freeze immediately then defrost overnight).

Use 2 skillets to cook the chicken and vegetables at the same time, if you can.

Heat 1 tbsp oil in a heavy based skillet over high heat until smoking. Add vegetables to cover the base of the pan in a single layer without too much overlapping (I cook in 3 batches). Spread out, leave for 45 seconds (to char it).

Toss quickly then spread out. Sprinkle with salt and pepper. Leave 45 seconds, toss then spread out, then leave 45 seconds. Remove onto platter and repeat with remaining Vegetables.

Heat 1 tbsp oil in a large skillet over medium high heat. Add chicken and cook for 3 to 4 minutes until caramelised. Turn and cook the other side for 3 – 4 minutes.

Remove onto a plate, cover loosely with foil. Rest for 3 minutes then slice.

Warm tortillas using chosen method.

Pile peppers and onion onto tortilla. Top with chicken, drizzle with sour cream, squeeze over lime juice. Fold, devour and be happy.
