I was out on my parent's boat last week and saw a couple boats with a grill that hooks on to the side of the boat. They were bbqing hot dogs, kabobs, even corn on the cob. Looked good!
There was also a pizza boat out on the lake that cooked pizzas and then smaller boats went out to take orders and delivering.
I just do the boring stuff like subs, chips, fruit, cookies. ;)
