Preparation

1. Preheat oven to 375°.

Reduce heat to medium-low; sprinkle flour over vegetables. Cook for 5 minutes, stirring frequently. Stir in milk and broth. Increase heat to medium-high; bring to a boil. Reduce heat, and simmer 5 minutes or until thickened. Add chicken, peas, salt, and pepper.
3. Spoon mixture into a 3-quart baking dish. Place 1 phyllo sheet on a large cutting board or work surface (cover remaining dough to keep from drying); lightly spray with cooking spray.
