Chicken Florentine Wrapped in Pastry

1. Heat the oven to 400 degrees F. Beat the egg and water in a small bowl with a fork. 2. Pound the chicken to 1/4-inch thickness. Cut each chicken breast in half. Coat the chicken with the flour. 3. Heat the oil in a 12-inch skillet over medium-high heat. Add the chicken and cook until well browned on both sides. Remove the chicken to a plate. Cover the plate and refrigerate for 15 minutes. 4. Stir the spinach and nutmeg in the skillet. Reduce the heat to medium. Cook for 5 minutes or until the mixture is hot, stirring often. 5. Unfold 1 pastry sheet on a lightly floured surface. Roll the pastry sheet into a 14-inch square. Cut the pastry sheet into 4 (7-inch) squares. Repeat with the remaining pastry sheet, making 8 squares in all. Brush the edges of the pastry squares with the egg mixture. 6. Place 1 chicken piece in the center of each of 4 pastry squares. Spread each with 1 teaspoon mustard and top with about 1/4 cup spinach mixture. Top each with another pastry square. Press the edges to seal. Brush the pastries with the egg mixture. Place the pastries onto a baking sheet. 7. Bake for 25 minutes or until the pastries are golden brown. 8. Serving Suggestion: Serve with sliced cherry tomato halves tossed in balsamic vinaigrette and sprinkled with feta cheese. For dessert serve warm gingerbread squares topped with lemon sauce.
