I'm in boarding school, and the food is horrible, so up until now, I've been bringing canned soup that I brought over from America, but I'm running out, and I still have a month to go :o I'm planning on buying some containers and bringing food I make over the weekend as food for the week. I'm facing the problem of not knowing how long food will last, so I don't know what kind of food I need to bring, because I need to make sure it doesn't expire within a week. What kind of food would that be?
PS. I have no way of heating it up except for a microwave.
