Depends on my mood. If I'm RAVENOUS I'll get a boneless banquet with gravy and a Pepsi. If I want to take my time, I'll get a 3 piece. Boneless box usually wins as I'm always hungry.
I've had a whole bucket and a super duper boneless box, not sure what it is called but it has about 8 pieces, by myself before (separate occasions!) but nah nearly all the time I get the Wicked Zinger Meal. Sometimes ask for no lettuce.
