I found this recipe on the Simple Daily Recipes website. Never in my life had I heard of slang Jane - but I do love a good cucumber and onion salad! This is reputedly "The Thing" in East Texas to put on your black-eyed peas or fried okra.
Dice the cucumbers, tomato and onion into the same size pieces, and toss together in a medium bowl. Pour in enough cider vinegar to cover the salad. Season with sugar, salt and pepper. If the vinegar flavor is too strong for you, cut it with water, one tablespoon at a time. Salt will help soften the vinegar taste, too.
