Food at the footy is an interesting spectator sport , mine was hot dogs in a thermos like others if I had a young blokes to feed
When we played Melbourne  it was spot the best cheese and  meat platter with club sandwiches 
Another time someone brought a fully cooked meal in containers for the family, they really needed a trestle , 
But my favourite was when in the function room ( Brisbane) a couple of ladies brought big lunch boxes , stuffed them full of pies and sausage rolls from the tables so there were none left by the time I got there, they even brought their own sauce
