I found a recipe similar to this on another frugal web site. At first glance this may not appear "poor man", but rest assured it is. Everything used here was purchased on sale, bulk, or at our local Dollar Tree store. It cost me about $1 per person for entire meal. This fed a family of four with enough for seconds and in one case thirds. My best friend used store bought family size can and it fed her family of 6.
My kids all time favorite is baked bean soup. I use left over homemade baked beans and process in food processor till smooth. Place in saucepan with a tad of water to bring to soup consistantcy. I add a 4 strips of crisp bacon coarsly chopped, ladel into bowles, sprinkle with grated cheese and scallions (optional). Serve with grill cheese sandwich. YUMMY!!
