Preheat Gridiron to medium-high and prep ingredients.

Add pepper.
Let the chicken cook while you work on the filling. Pour the chicken stock into the Wok insert.
Add chicken bouillon.
Place butter in Wok.
Add onions.
Add carrots.

While filling simmers, place one of the pie crusts in the bottom of the Cast-Iron Kettle insert. The dough should be soft, push down to fill entire area evenly.
When chicken is done (temp in middle of breast is 165 degrees F), remove from grill and slice into 1 in pieces.

When mixture starts to thicken, add the chicken and stir.
Remove Wok insert and place Kettle insert in Gridiron. Pour chicken mixture into Kettle insert.
