My wife is both allergic to the oil in onions, AND we are both diabetic. I have a recipe that I created for her, that very closely resembles the taste of KFC coleslaw, without the onion oil, and also cuts down on the carbs, for our diabetes.
Mix oil, dried onion, Tarragon vinegar, Miracle Whip and Splenda together and set aside. It is very important to mix the dried onion into the wet ingredients, first, to allow them to absorb the oil and moisture.
Grate carrots and cabbage, together.
Pour Liquid over Carrot/Cabbage mixture.
Refrigerate in an air-tight container, for at least 2 hours, before serving.
