Beets and mandarin oranges are plentiful in my local grocery store, as both are in season.  I recently had a delicious beet salad with mandarin oranges at the Trellis Restaurant in Kirkland.  Then last week I had a great beet salad with mascarpone (no mandarins) at Tulio in Seattle.  I liked both salads very much and decided to combine the flavors from both salads and came up with what you see here.  This is about as easy a salad as you can get other than stopping at your local salad bar (which I am never in favor of).  You do have to roast the beets, but it is quite easy,
