Preheat your grill to about 400 degrees
While the grill is heating -sprinkle your seasonings on your roast & rub them in
Once your grill is proper temperature - place roast on to sear
Once meat sears (3-5 minutes each side) reduce heat to about 375 degrees & don't touch - allowing to cook for about 20-25 minutes on one side before flipping over.
*Note- the colder it is outside the longer it will take for the meat to cook even though the grill is a certain temperature. Also- with gas grilling in the cold- the gas will behave differently than in warmer climates. You will need to watch your temperatures of your grill & meat closer through this process.
After the roast has cooked on each side brush on your BBQ sauce & cook an additional 10-15 minutes on each side
Remove when roast reaches 170 degrees
Let to sit 10-15 minutes before cutting to allow the juices to cure
Thinly slice & enjoy.
