Market Basket Recipe: Radish Sandwich

I've been getting a ton of French Breakfast Radishes (and this week I got Ping Pong Radishes too) in my Market Basket.   Apparently the French eat their radishes on a piece of buttered french bread. I happened to get a Martha Stewart email one day, and she had a "recipe" for Radish Sandwiches also.  I've never heard of anyone eating these, but apparently they do!

Here's mine. Pretty simple, but really good!
