Preheat Traeger grill to 225*.
Apply a thin coat of almond oil on all sides of the meat, coating well.
Season the meat with the Italian seasoning blend and allow the meat to sweat for 10 minutes.
Insert a Meater thermometer probe in the thickest part of the roast and pair the probe with the app.
Set the desired temperature to 202*.
Place the seasoned meat in the preheated grill and cook for 60 minutes.
After an hour has elapsed, turn on your griddle or heat up a cast iron pan until very hot.
Transfer the meat to the hot griddle or pan and sear on all sides until golden brown.
Place the seared meat in the bottom of a heavy dutch oven pan.
Add the beef broth, seasonings, butter, and peppers and mix to combine.
Cover the pan with a lid and return it to the grill.
Turn up the grill to 275* and allow the meat to cook for about 5 hours, checking occasionally.
When the meat reaches an internal temperature of 202*, remove the pan from the grill and allow to cool on the counter for 15 minutes.
Using gloved hands or two big forks, shred the meat until an even consistency is achieved.
Return the shredded beef to the pan with juices and include the juices when serving.
Serve the Italian Beef straight off the Traeger on warmed hoagie rolls with additional peppers if desired.
