Hospital stay, What to pack for food?

hannah • Mom of three boys and due with #4 in July.
I don't eat hospital food and I'm a vegan which means that I will have to carry my own food. Are you in the same situation? What will you bring with you? My hubby will be with the kids and might not be able to bring the food on time and I don't want to wait on him. Just looking for some ideas of what others have done.
