In a small bowl whisk together the yogurt, olive oil, paprika, salt, pepper, cumin, cinnamon, onion powder, red pepper lemon garlic, and cilantro until combined.
Cut the chicken thighs into 1 1/2 inch pieces and place into a large bowl and pour the marinade over the chicken and toss until coated. Place into the refrigerator for at least 1 hour but overnight for optimal flavor.
Remove the chicken from the refrigerator and thread the chicken pieces into the skewers, don't over crowd the skewers.
Heat a grill on medium high heat, grease the grates with a little olive oil and place the kebabs over direct heat grill for 13-15 minutes turning every couple of minutes.
Remove from the grill and let rest 5 minutes then serve!
Notes
You can use chicken breasts if you prefer but the cooking time may be quicker.Wooden skewers can be used but soak them in water for about 1 hour before threading the chicken on.Add chunks of onion or bell peppers in between the chicken pieces.
