We've all heard the saying "cool as a cucumber." This veggie sandwich truly is. You'll look at cucumbers in a whole new "lite" once you've sampled this gourmet gem.
2 thin slicing cucumbers, peeled, sliced paper thin
Put cucumber slices into a bowl. Toss with salt. Sprinkle with vinegar. Toss and allow to stand 1 hour. Drain well in a colander. Blend butter, tarragon and chervil together. Lay out your slices of bread and butter 1 side of each bread slice. Cover 15 slices with cucumbers, dividing evenly. Close sandwiches and trim crusts. Cut into rectangles with a sharp knife. Serve.
