Begin by preparing pellet grill and heating to 225*F.

In a large bowl, combine all ingredients for the meatloaf.

Once the ingredients are combined, shape and form the meatloaf onto the sheet of foil.

Roll up the sides to secure the meatloaf.

Once the pellet grill reaches 225*F, carefully place the meatloaf on the grill for 3 hours or until the internal temperature reaches at least 165*F.

Prepare the sauce ingredients in a small saucepan.

Combine the ketchup, sugar, chopped onion, liquid smoke, and garlic powder.

Once it reaches a low bowl, whisk well until the sugar is dissolved.

In the final hour of cooking, carefully open the grill and use a brush to brush the sauce evenly onto the meatloaf.

Let cook an additional hour until the internal temperature has been reached.

Carefully remove and place on a cutting board or serving tray and serve.
