In a bowl, toss chicken well in olive oil. Add remaining ingredients, coating well. Let chicken marinate, covered and chill for at least 1 hour and up to 2 hours.
Transfer chicken with marinade to a flame-proof flat dish just large enough to hold it in one layer and broil under a preheated broiler, about 3 inches from heat 6 to 8 minutes or until cooked through. Serve chicken and marinade over cooked spaghetti. Serves 4.
