Boneless Pork Roast with Caramelized Onion (Zwiebel Schweinebraten)

Having been raised by a German mom (Bavarian, to be exact), I find this traditional roasted pork with caramelized onion, served with potato dumplings to be one of my favorite childhood meals. It's very simple to make. Please visit my food blog to see how I made this dish on my food blog at: http://foodiewife-kitchen.blogspot.com/2010/01/zwiebel-schweinebraten-mit-kartffel.html
