Beans from a can, champignons from a glass, bit of corn from a can. Put it on a tortilla with a bit of salsa for flavor. I add some flax seeds cause they are supposed to be good for your intestinal health. Obviously this tastes better when you take some time to prepare it in a pan, but it's cheap, very filling and takes a few minutes to prepare at most. I like to eat it cold on hot summer days.
