Ingredients:
Cucumbers, sliced
Onion slices
Apple Cider Vinegar (although, I didn't have any and used 90% rice vinegar and 10% balsamic)
Water (equal parts to vinegar)
Salt and Pepper
Put them all in a tupperware or a bowl with a seal, and throw in the fridge overnight. The serve as a side to anything from burgers to brauts.
