Cucumber salad

I tend to think about this salad more in the summertime, but there's absolutely no reason not to serve it at other times.  Use an English cucumber, and slice it paper-thin with a processor if you've got one.  I did this one by hand, and my slices are a bit thicker.  I used shallots instead of the more traditional red onions, and doused it all with oil and vinegar.  Sprinkle with sesame seeds just before serving.
