In a small bowl place the chili powder, brown sugar, smoked paprika, pumpkin pie spice and salt in the bowl. Mix well until incorporated and blended together. Set to the side.
Place the sweet potatoes, apples, and butternut squash on a large rimmed baking sheet. Pour the grapeseed oil on top and sprinkle half the seasoning over the vegetables. Mix well with hands. Place in the oven and bake for 10 minutes.
While the vegetables cook, sprinkle the pork chops with the remaining seasoning. Then, carefully remove the baking sheet from the oven and place the pork chops on top.
Bake for 30 minutes or until potatoes are tender and the pork chops read an internal temperature of at least 145 degrees Fahrenheit. *Can go up to 165 degrees Fahrenheit. Divide evenly among plates and enjoy.
