Here is our classic summer barbecue cucumber salad recipe. The recipe is pretty approximate, but here goes:
Cucumbers, peeled, and slices into rounds
White onion, chopped into 1.5″ or so long chunks.
Sour Cream
Salt
Pepper
Sprinkle a large amount of salt on the cucumbers and onions, let them sit for a little while, then add sour cream, and possibly more salt, and pepper. Let sit for a couple hours for best results. Use more salt than you think.
