Pull filo dough out of freezer to thaw before starting. Shred chicken from rotisserie and set aside. Preheat over to 400.

Once filo dough is thawed roll out to 12-inch square and press into 2-quart round dish. Trim excess and prick bottom with fork. Cover with aluminum foil and bake 25 minutes until golden brown (may need to uncover toward end of 25 minutes).

While baking the bottom dough later, prepare the filling. In a large sauce pan heat olive oil of medium heat. Add onion, celery, bay leaf and seasoning and heat until onion is translucent. Add butter; remove bay leaf and add flour. Cook 3 minutes until flour starts to brown, then add flour. Stir mixture until it begins to boil, allow to thicken. Add chicken and frozen vegetables. Mix to combine and remove from heat.

Once bottom dough is cooked, add filing. It may overflow. Now roll out your second sheet of filo dough. This will be your pie top. Place over filling and tuck around edge of round dish. Make small cuts in the top dough.

Place round dish on a baking sheet and place in oven (to avoid a big overflow mess). Bake at 400 for 30 minutes.

Let cool and eat!
