I'm wondering the same! Seems like "Commerce" is more geared towards ordering non-food type items. I'd like to be able to input what we're selling right at the time, and how much we have available, and let customers pre-order. There's got to be a way!
Also, I don't want customers to have to go to each individual page for each available item. Would be great if they can check items and quantity all on one page.
