In a large bowl, combine olive oil, ground cumin, paprika, turmeric, ground coriander, ground cinnamon, minced garlic, lemon juice, salt, and pepper. Add chicken and coat well, then marinate for at least 30 minutes.

Preheat a grill or non-stick pan over medium-high heat, adding oil to prevent sticking.

Cook marinated chicken for 5-7 minutes on each side, checking for golden crust and an internal temperature of 165°F (75°C).

While chicken is cooking, whisk mayo, minced garlic, lemon juice, and salt in a small bowl until smooth.

Once cooked, let chicken rest for a few minutes, then slice against the grain and serve in warm pitas or on plates with garlic sauce and veggies.
