Awhile ago, in Costco, I was standing behind a man who was buying boxes and boxes of canned green beans. That's all he was buying and I couldn't help myself - I just was so curious what all those green beans were about, so I asked. He said he added them to his dog's food as a way to extend their purchased dog food. He said his dogs love the green beans and it saves him on dog food. Just thought that was kind of interesting!
