Fire up your Big Easy.
Score the bologna as desired.
Rub all sides of the chub with the mustard or whatever you are using.
Place chub in the Big Easy basket and lower into the cooker.
Cook for about an hour. Keep an eye on the chub after 40 minutes. Depending on conditions it might char quicker than 1 hour. The chub is already cooked, so you're just giving it some color, extra flavor and good looks.
Remove and let rest for 10 minutes before slicing as desired.
