Preheat oven to 400 degrees. Spray a 13X9 inch baking dish with cooking spray. Place salmon in dish. Season with pepper. Slice one clementine into quarter slices. Squeeze juice of 2 quarters over salmon. Then place thinner slices of that remaining clementine on top of salmon, followed by sprigs of rosemary. Bake for 20 minutes or until fish is flakey.

Cut new potatoes in half and boil potatoes in a medium sized pot until soft. Approximately 10 minutes.
