Wash and pat dry the chicken thighs. Sprinkle the skin side with a little bit of the spice blend, then rub it in.
Warm the oil over medium high heat in a large pan.
Place the chicken thighs into the pan skin-side down, then reduce heat to medium.
Brown the thighs for 5 minutes, then flip them over and cook on the other side for 1 minute. Flip them back to the other side (skin side down) and brown for five more minutes, then remove the chicken thighs from the pan and place them on a plate.
Reduce heat to medium-low and place the onions and garlic in the pan. Cook for 3-5 minutes, or until slightly softened.
Add the remaining spices, diced tomatoes with juice, olives, chickpeas, lemon zest, lemon juice and chicken broth to the pan along with the onion and garlic.
Use tongs to nestle the chicken thighs down into the mixture with the skin side up.
Bring the liquid to a boil, then reduce heat and simmer on low - uncovered - for 5 minutes.
Cover and simmer for 20 more minutes, or until the chicken is cooked through. Taste and add more salt if needed, then serve over rice, cauliflower rice, or couscous. Garnish with chopped fresh cilantro or parsley.
