The beautiful bounty of summer vegetables rarely needs much adornment and this Crispy Crunchy Cucumber Salad is a classic example of simplicity allowing the vegetable to shine.
Using a mandoline, slice the cucumbers about 1/16 of an inch thick. If you don't have a mandoline, slice them as thinly as possible with a chef's knife.
Cut the onion into quarters and slice each quarter as thinly as possible. If you're brave enough, you can do it on the mandoline.
Pour the olive oil and red wine vinegar over the thinly sliced cucumbers and onions. Stir to coat the slices well. Add salt and pepper liberally to taste.
