I would recommend cooking any of the Lipton noodle dinners that come in a pouch, and then dump in a pouch of tuna. It's filling, tastes more or less pretty good, provides a lot of calories, necessary fat and protein. The Lipton dinner costs about 1.79 or so, and the tuna a little less, so you get a cheap, easy-to-prepare meal. Of course, my hunger was off the chart, so I always ate the entire Lipton package in one sitting.
