Our mom was always home to cook for us. Many times we were served just white bead and gravy for dinner. She was a great cook, and we ate well most of the time.
When I moved away from home and became an "adult" I ate a lot of gummy Japanese rice with just soy sauce on it for some flavor. On Friday, payday I would splurge and pour a can of Campbell's soup over the rice instead and savor each bite. I had a Panasonic rice cooker and it got lots of use. I could eat for 4 cents per day. Potato soup was another staple.
I don't miss those days of being broke.
I do remember one time I drank a 6 pack of beer and ate a bag of Doritos for dinner, likely on payday. I only did that once, as there was no one to say you shouldn't do that.
