Fish on a Stick

Preheat broiler. Place a metal rack inside a rimmed baking sheet.

Thread 1 piece of fish onto each of 12 (6-inch) skewers (cut off pointy tips of skewers beforehand, if desired); sprinkle fish with salt and pepper.

Place pumpkinseeds in a food processor; pulse until finely ground. Transfer to a shallow dish; stir in lemon rind and parsley. Place olive oil in a shallow dish.

Dip fish in olive oil, then in seed mixture, turning to coat evenly. Place on rack in pan. Repeat with remaining skewers. Coat both sides of fish with cooking spray. Broil 2 minutes on each side or until pumpkinseeds begin to brown and fish is firm. Serve with tzatziki sauce.
