In a mixing bowl, combine yogurt, tomato paste, paprika, chili powder, coriander, cumin, salt, garlic powder, onion powder, sumac, and lemon juice.
Add the chicken strips and mix well until every piece is coated.
Let the chicken marinate for at least 20–30 minutes (or refrigerate up overnight for deeper flavor).
Heat 2 tbsp oil or ghee in a pan over medium-high heat.
Add the marinated chicken and cook for 8–10 minutes, stirring occasionally, until the chicken is browned, slightly crispy, and fully cooked through.
Turn off the heat and set aside.
Mix Greek yogurt, mayo, crushed garlic, lemon juice, olive oil, sumac, salt, and pepper.
Taste and adjust seasoning as needed.
Keep refrigerated until assembly.
In a small bowl, combine sliced onion, tomato, sumac, lemon juice, salt, and pepper.
Drizzle a little oil or ghee into a heated pan.
Place one tortilla onto the pan.
Immediately sprinkle mozzarella cheese over the tortilla.
Add cooked chicken on top of the cheese.
Fold the tortilla over to create a half-moon shape.
Cook until deeply crispy and golden on both sides.
Remove from the pan and gently open the tortilla.
Add a spoonful of yogurt sauce and some prepared salad.
Close, press lightly, and enjoy warm.
