The cumin-and-coriander rub in this grilled chicken thigh recipe pairs deliciously with a minty cucumber salad. Chicken thighs can vary widely in size. Ask your butcher to hand-select 4 large thighs for this recipe. If you can only find small chicken thighs, cook 2 per person and reduce the grill time slightly.
