Semi Pulled Beef and Pepperoncini Peppers

Didn't want just a standard pulled beef so I went with beef and pepperoncini peppers. I recall someone here did it before but couldn't find the recipe. Started out with a 3 1/2lb chuckie on the egg at 250 till it hit 160IT and then I cut it in half and put in a divided foil pan. One side for sammiches and one side for soup meat. The sammich side had pepperoncini peppers,red onions and beef broth added(gonna use broth for soup), the soup side was onions and broth. Bumped up the temp to 350 and put back on the egg covered in HDAF till it hit 205 then uncovered, pulled the meat and put back on egg uncovered for bout 1 1/2hrs. Could've gone longer but I want some broth left over for soup later And the sammich on ciabatta buns with fresh slaw & fries I was really impressed with the way the beef took on the pepper taste but wish the meat had pulled better. IDK why it didn't pull well cause I generally don't have a problem getting a chuckie to pull using this method. Only thing different was wrapping it in a pan instead of just wrapping in HDAF. I will do this again.
