Coat the chicken in the spice mix (oregano, garlic powder, cumin, paprika, salt, and pepper) and rub well.
In a frying pan, heat the olive oil over medium heat and cook the chicken for approximately 3 minutes on each side. Remove the chicken from the pan and set it aside.
In the same pan, add the red and green peppers and onion, sauté for about 4 minutes.
Add the basmati rice to the pan along with the spices (salt, paprika, cumin, and turmeric). Toast for 2 minutes.
Pour in the water, cover the pan, and let it simmer for 8-10 minutes until the rice is cooked.
For the sauce, add all the sauce ingredients (Greek yogurt, mayonnaise, garlic cloves, cilantro, salt & pepper, and lemon juice) to a blender and blend until smooth.
Serve the spiced chicken over the vegetable rice and drizzle with the creamy sauce.
Protips
Ensure that the chicken is cooked through. The internal temperature should be at least 165°F (74°C) when checked with a meat thermometer.
If your sauce is too thick, add a bit of water or olive oil to thin it out.
You can garnish the dish with fresh cilantro leaves for added flavor and presentation.
