The 22in OTG fits quit a bit of food on it. I can comfortably fit enough food on it w/ direct cooking for 4-5 people. For indirect cooking you lose some space and it might be a tight squeeze if you are trying to fit veggies etc on at the same time the meat is on.
I typically cook on my OTG for myself and 2 roommates (both guys) and we have leftovers that I can bring for lunch the next day and eat for dinner the next day.
