Unroll crescent dough and separate into 4 rectangles; seal perforations. Place a salmon fillet in the center of each rectangle; sprinkle with salt and pepper. Spoon spreadable cheese over each; top with spinach. Fold dough over filling and pinch edges to seal.
Place on an ungreased baking sheet. Bake at 400° for 20-25 minutes or until golden brown.
