Place 1/2 of fish fillets on each piece of foil. Sprinkle each with lemon juice and paprika. Place 1/2 of the onion slices on each fillet. Combine parsley and chives. Roll potato in parsley mixture. Arrange 1/2 potato sticks around each fillet. Season each with salt and pepper. Fold foil and secure tightly. Bake 325 deg. for 40 minutes. Open foil and dot each with 1 ts margarine. Makes 2 servings for dinner. May also be microwaved 12-15 (not in foil) This is an old WW recipe and should be adjusted according to today's weights etc.
