Wash garden fresh cucumbers under cold water to get any dirt off. Peel cucumbers. Slice onions and cucumbers and place in a large bowl. Stir together. Sprinkle a good 1-2 Tablespoons of salt over the veggies and stir well again.
Let veggies set on the counter for a good 15 minutes, then drain off the liquid that has accumulated.
Mix the Miracle Whip and black pepper (to taste) into the veggies until well mixed together, Cover and refrigerate until ready to serve. These taste better the longer they are allowed to chill in the frig.
