Preheat oven to 375. Drain spinach in a strainer, using the back of a spoon to press out excess liquid. Combine drained spinach, mushrooms, ricotta cheese, pine nuts, nutmeg, egg, seasoned salt and 2 tbsp of the parmesan cheese; set aside. Brush each sheet of filo with melted margarine or butter; stack filo sheets. Cut filo crosswise into 1/4s and lengthwise into 1/3s to form 12 (4-layer) squares. Gently press each square into a muffin cup. Spoon 1/4 cup spinach mixture into each filo-lined cup. Sprinkle with remaining 2 tbsp parmesan cheese. Bake 25 minutes or until golden brown and filling is set. Remove from oven; let stand 5 minutes. Remove from cups.
