Preheat oven to 375F and spray a large baking sheet with some nonstick cooking spray.
Cut the raw chicken into 1-2 inch cubes.
In a bowl, mix together the ¾ cup of nonfat Greek yogurt, fresh lemon juice, cumin, turmeric, paprika, cinnamon, salt, pepper, and garlic.
Add the cubed chicken and mix well - make sure all the chicken is coated.
Cut the onions and peppers into slices, then cut the cherry tomatoes in halves.
Spread the chicken, onions, peppers, and tomatoes on the sheet pan. (I kept everything separated on the sheet pan- see picture).
Bake it in the oven for 25 minutes (or until chicken is cooked through).
Divide into 6 servings and enjoy with a drizzle of the white sauce!
To make the drizzle white sauce, put all the ingredients into a food processor or blender and blend for a few minutes.
