What’s your favorite poor person meal to cook?

Not a poor person by any means, but I can be cheap and/or very lazy when it comes to fixing a quick snack just for myself! I have never tried this myself but have heard stories of “depression soup,” where one just empties the contents of a few ketchup bags into some warm water – viola, tomato soup! If I’m looking for a quick protein snack, sometimes I’ll just open up a small can of tuna packed in water, drain the water, add a dollop of mayonnaise and a touch of relish – use a fork and delicately mix it and eat it right out of the can.
