A&W ? I,ll stick with my own mozza mushroom burger. The past year or so,I have gotten away from bread crumb and egg binder. I just go straight ,salt,pepper and some seasoning. I keep the coals in the middle and put the burgers around it. Cover 15 min with the top vent open 1/2 . Bottom pot is always open full . Flip and another 15 min. Put in the middle for 5 min to get a bit of char, flip,mushrooms, cheese and cover for another 5 min. They turn out so nice and juicy. Let the meat tell ya when it,s ready.
