Fire up your Char-Broil Big Easy.
Remove the roast from the bag. Do not remove it from the twine netting.
Sprinkle your rub on all sides of the roast, rubbing it in as you go.
Place roast in the Big Easy basket and lower into the cooker.
After 45 minutes, begin checking the meat temperature every 5 minutes or so. Once it reaches 165 F remove the roast.
Let rest 15 minutes before slicing.
