This is my version of a coleslaw I tasted many years ago at a catered event. It's close but not precisely the same. However it's a refreshing change from those familiar too-creamy coleslaws. The salad base is made up of 4 vegetables that start with the letter C, hence the recipe name. Cabbage, corn, cucumber, and cilantro team up with onion and a lime and mayo dressing. You can keep adding more C vegetables if you want - carrots, celery, chives subbed for green onions, etc., but I prefer the flavors and simplicity of just those listed below. A nutritious addition to your summer picnics.
