1. Have ready a 9-by-2-inch round baking dish or glass pie plate.
2. In a large skillet, heat 1 tsp. of the oil over medium heat. Add red pepper and cook, stirring often, for about 4 minutes just to soften it. Remove to a plate and set aside.
3. Put chicken pieces in a medium bowl and sprinkle with 3 Tbsp. of the flour. Toss chicken to coat it lightly with flour. In the large skillet, heat remaining 1 Tbsp. of oil. Add chicken pieces and cook just to brown them on both sides, about 10 minutes. The chicken is not fully cooked at this point. Remove to a clean plate and set aside.
4. In a small bowl, stir together remaining 2 Tbsp. of flour and 1?3 cup water until smooth. Set aside.
5. In the large skillet over medium heat, heat broth until it just begins to simmer, scraping with a wooden spoon to loosen any brown bits stuck to the skillet. Whisk in dissolved flour mixture, whisking constantly until it's smoothly blended. Bring to a gentle boil, stirring often and adjusting the heat as necessary, and boil for 1 minute. Sauce will thicken slightly to the consistency of thick syrup. Remove about 1/2 cup of sauce to a small bowl and whisk in mustard.
6. Add chicken pieces to sauce in skillet. Continue cooking for about 10 to 12 minutes until chicken is cooked through and no pink remains. Stir in red pepper.
7. Return mustard mixture to skillet and stir to combine it smoothly. Taste sauce and add salt and pepper if needed. Transfer filling to baking dish. Set aside to cool for about 15 minutes.
8. Preheat oven to 375 degrees F.
9. Lay out 6 phyllo pastry sheets in a stack. Immediately cover phyllo completely with a damp dishtowel. Spread one sheet of phyllo on work surface and use a pastry brush to brush it lightly with butter, then sprinkle it lightly with salt. Crumple it into a loose ball (like a piece of newspaper) and place it on top of filling. Repeat with remaining 5 sheets of phyllo, arranging them to cover filling.
10. Bake for about 15 minutes, until filling is hot and phyllo crust is golden. Use a large spoon to scoop out servings.
