Spicy Tunisian Grilled Chicken

Make Ahead Tip: Store the rub in an airtight container for up to 3 months; coat the chicken with the rub up to 30 minutes before grilling or broiling.

Note: It's difficult to find an individual chicken breast small enough for one portion. Removing the thin strip of meat from the underside of a 5-ounce breast--the chicken tender--removes about 1 ounce of meat and yields a perfect 4-ounce portion. Wrap and freeze the tenders and when you have gathered enough, use them in a stir-fry or for oven-baked chicken fingers. If you can only find chicken breasts closer to 8- to 9-ounce each, you'll only need 2 breasts for 4 servings--cut each one in half before cooking.

Tip: Oiling a grill rack before you grill foods helps ensure that the food won't stick. Oil a folded paper towel, hold it with tongs and rub it over the rack. (Do not use cooking spray on a hot grill.) When grilling delicate foods like tofu and fish, it is helpful to coat the food with cooking spray.
