Wash cucumbers just before using. Unless the skin is waxed, the cucumber doesn't require peeling; for more flavor, score the skin with the tines of a fork before slicing. The seeds become bitter as the cucumber ages, so remove the seeds from larger cucumbers. Add cucumbers to any tossed salad, or combine cucumber slices with thinly sliced red onion, fat-free yogurt, and fresh dill. For a fresh pickle, slice and combine with water, vinegar, and a little salt.
