What is the cheapest meal you have ever made or had the pleasure of eating?

We made vegetable stew after Thanksgiving. Which is where you take all the leftovers (vegetables within reason) put it in a pot together with tomatoe soup and call it a meal. A friend of mine thought I ruined all the leftover... it is more like all good things at once for me. My friend says my vegetable soup reminds him of homeless camp. Im about to enjoy it for days. So what is a "cheap" meal you very much enjoy?
