Mix the chicken with all the marinade ingredients and marinate for 20 to 30 minutes.
Heat 2 tbsp oil in a pan, add the marinated chicken, and stir-fry for 4 to 5 minutes.
Cover and cook on low to medium heat for 10 to 25 minutes, until cooked through.
Uncover and cook for 2 to 3 minutes more, until the water is absorbed and the oil separates.
For the salad, combine the cucumber, carrot, onion, coriander, and mint in a bowl. Add black salt, vinegar, and black pepper, and mix well.
For the sauce, mix all the sauce ingredients until smooth.
Brush a pan with oil and place a tortilla on it. Add mozzarella, top with chicken, fold in half, and toast both sides until light golden.
Open the tortilla, add salad and sauce as desired, and fold again. Serve immediately.
