1. Mix together the oil, oregano, salt, pepper, and lemon zest in a bowl. Add the chicken ensuring both sides are fully coated. Cover and refrigerate for 1 hour.
2. Preheat grill to medium-high. Remove chicken from marinade. Grill uncovered for 6-8 minutes per side. ! Make sure chicken is fully cooked throughout ! Transfer chicken to a cutting board; drizzle with lemon juice. Leave to rest for 5-20 minutes.
3. Whilst the chicken rests, place the pitas on an unoiled grill. Grill uncovered until warmed and slightly charred – about 2 minutes per side. Remove from grill and spread 2 tbsp of tzatziki over each pita
4. Slice the chicken crosswise and then divide lettuce, tomatoes, onion and chicken evenly among the pitas.
Swap out the chicken for grilled peppers, corn, mushrooms and even some hummus for veggie pitas 😊
