Preheat the oven to 375 degrees.
Prepare your crust according to the directions. Place it in a pie plate, reserving a small chunk of dough for the top.
In a large pan, heat the vegetables and the butter over a medium-high heat.
Once the vegetables are softened and the butter melted, add in the arrowroot powder and mix to combine.
Once combined, add in the chicken broth, salt, pepper, and garlic powder and turn to a high heat.
Once the sauce starts to thicken, turn heat to low and add in the chicken.
Cook on the stove for about 5 minutes and then add the mixture into your pie crust.
Taking the extra ball of dough, roll it out and cut out a few shapes or just roll into balls and flatten and then place them on the top.
Bake for about 20 minutes or until the crust is golden brown.
Enjoy!
