Shiitake mushrooms and barley soup

I had to put dinner together quickly today as I had a meeting to attend, so came up with a relatively simple meal. I found great shiitake mushrooms at the farmer's market this past weekend, looking unlike other shiitakes I've found (and quite large, maybe 2" in diameter), and wanted to try them very simply, so I just sauteed them in artisanal extra virgin olive oil - they were good! I made a barley soup and served leftover spiral potatoes from late last week.
