Preheat your oven to 375°F (190°C).
In a large skillet, melt the garlic butter over medium heat.
Add the diced potatoes to the skillet and sauté for about 5-7 minutes until slightly tender.
Stir in the garlic butter turkey and ham, cooking just until heated through, about 4-5 minutes.
Sprinkle the flour over the mixture and stir to combine, cooking for an additional 2 minutes.
Add the frozen peas, dried thyme, salt, and black pepper, mixing well.
Remove the skillet from heat and let the mixture sit for 5 minutes to thicken further.
Place one pie crust in a pie dish and fill it with the turkey and ham mixture.
Cover with the second pie crust, sealing the edges and cutting small slits on top for steam.
Bake in your preheated oven for 30-35 minutes until the crust is golden brown.
Let the pie cool for 10 minutes before slicing and serving.
