My niece calls this recipe sour cucumbers and I'm sure that lots of people make a variation of this....it's wide open for interpretation.
1 seedless cucumber slice really thin
1/2 small white onion sliced thinly
black pepper--lots and lots
Make a vinegarette with whatever ratio you like. We usually make it with more vinegar than oil because my niece loves the sour. Allow the mixture to marinate for 1-3 hours. It only gets better when it sits longer
