For the marinade, mix together the lime juice, 3 tablespoons of olive oil, the dried oregano and the coriander powder. Add the chicken strips and refrigerate for 4 hours.
Fry the chicken in the marinade in a high pan. Add the onions and peppers and continue frying until the vegetables are cooked through but still crisp. The meat is best served in a hot pan. Serve with the sour cream, the toasted sesame seeds, the guacamole and the fresh chopped coriander. Put a little of each on a tortilla, roll it up and enjoy.
Tip:
Also tastes very good without chicken, then double the amount of vegetables.
