Place the chicken tenders in a large resealable bag.
In a small bowl, whisk together olive oil, lemon zest, lemon juice, garlic powder, cumin, coriander, smoked paprika, and black pepper.
Pour the marinade over the chicken, seal the bag, and coat well. Refrigerate for 30 minutes to 1 hour.
While the chicken marinates, prepare the sauce by mixing Greek yogurt, lemon juice, and grated garlic in a medium bowl.
Stir in parsley and dill. Season with salt and pepper to taste. Cover and refrigerate until needed.
Heat a large skillet over medium heat.
Remove the chicken from the marinade and allow excess marinade to drip off.
Cook for about 4 minutes per side or until fully cooked and nicely browned.
Transfer to a cutting board and slice into bite-sized strips.
To assemble the Mini Chicken Shawarma Recipe, fill each mini pita with chicken, red onion, lettuce, cucumber, and tomato.
Drizzle with the yogurt herb sauce and serve immediately.
