Keep it simple
I have done pulled pork sammies, chip and a can drink before. Just wrap the sammie in 12x12 tissue. Set in a boat and add chips for $5-6 bucks. You can manage the boat and a drink standing up, walking or sit and enjoy
You store the cooked and prepared meat in pans on the pit/cooker, ice chests on stools behind serving table. Set out a big trash barrel helps. Need three people and only one handles money. (me LOL)
Something elses is frito pie. Chopped brisket covered in red beans, mild thin sauce, onions and fritos $5 bucks. Water sells big time.
Done several scooter rallies... drunks dig Q and will eat anything.
Just FYI...Use any of my input at your own risk.
