PREPARATION:
- Heat oil in large nonstick skillet over medium heat. Add potatoes, bell peppers, onion, mushrooms, garlic and spices; cook and stir 5 minutes. Let cool to room temperature.
- Preheat oven to 400°F. Unfold pastry sheets on floured surface. Roll each sheet into 12-inch square with lightly floured rolling pin; cut each square into 4 squares with sharp knife. Place about 1/4 cup filling in corner of each square; sprinkle with 1 tablespoon cheese.
- Brush small amount of milk on edges of pastry squares. Fold opposite corners over filling to meet each other, forming triangles. Press edges with fork to seal. Cut small slit in top of each triangle with knife. At this point, empanadas may be covered and refrigerated up to 24 hours or frozen up to 1 month.
- Place triangles on ungreased baking sheets; brush tops with remaining milk. Bake 15 to 20 minutes or until puffed and golden. Serve with salsa.
