Begin by preparing your pellet grill per the manual. This needs to be heated up to 225*F.
Once done, place a sheet of foil on a cutting board or in a 9x13 dish.
Place the roast on top of the foil and add the steak seasoning.
Combine the gravy with 1/2 cup of water.
Bring the foil up around the roast to create a "bowl" or packet for the roast.
Pour the gravy mixture evenly over the roast. Be sure the foil is up enough that it doesn't pour out.
Add the butter right on top of the roast.
Keeping the roast in the foil, carefully place on a heated pellet grill, this should be at 225*F.
Let this smoke for 3+ hours until the inteneral tempearture is at least 165*F. This will range from 3-4 hours, the key is to keep checking the temeprature during the cooking time.
Carefully remove and serve.
Remember to check the roast at 3 hours, then add additional time as needed to reach the correct internal temperature of 165*F.This recipe is for a 3-pound roast, additional time is needed for a larger roast.
