A great food that is very cheap to make is french toast. All you need to make french toast is bread, eggs, and cinnamon. Most people have bread and eggs and cinnamon can be bought in small containers at any grocery store and it's not expensive at all. French toast is also quick and very easy to make. Below is a video of my roommate and I making some french toast so you can see how to do it and how quick it is to do.
