SWISS, MUSHROOMS, ONIONS, SOURDOUGH GRILLED CHEESE SANDWICH

I finally got around to trying Big Girlfeet's recipe. We had them for dinner tonight, and loved them. Mine didn't look as good as the one pictured on her blog, but they really were delicious!
My sister, Jan, is here for a few days. We stayed up late talking. It's nearly 3 am, so I am cutting this short and going to bed.
