Need Plant ID

Need Plant ID

Okay, I've only recently started eating swiss chard. I sure as heck have never planted it, let alone not behind the stupid foot-crushing bird bath! This looks just like chard to me, but I need to be sure before I start eating it. If this is not swiss chard, what is it? How did it get there? If it is swiss chard, how do you go about saving seeds? It's always nice to grow things that have a story!
