This is such a simple and delicious way to enjoy the plethora of cucumbers you are likely enjoying that I can't really call it a recipe. I re-use the marinade for a week or so at a time since I have a container of these in the refrigerator almost all summer. A little bit sour and a little bit sweet coupled with a light crunch make these slightly addictive. Ok, very addictive.
Quick & Simple Marinated Cucumber Slices
For every cucumber you use, mix together 1/4 c white vinegar, 1/4 c granulated sugar, a pinch of salt and a pinch of pepper. Stir the concoction together until the sugar dissolves.
Wash and dry the cukes. Cut the cukes, peels left on or removed - your preference, fairly thin. Add to the marinade with thinly sliced onions if you like, and let marinate in a covered container in the refrigerator 2 - 24 hours.
Any less than 2 hours and the flavors haven't quite melded. More than 24 hours tends to begin to turn them mushy.
