My old cabbage shredder got "miss-placed". Loved it! Curious why light mayo. I have not used a brand I like and since I don't use it often I just go "whole hog" I also like add in other vegetables. I like it with cucumber, grapes, and apple - not all at once. And on occasion craisins.
Oh and you reminded me of the cabbage salad the neighborhood boys adored. Basically Napa cabbage, thick Chinese egg noodles, grapes, touch of Dijon, green onion, and a "Chinese chicken salad dressing", splash of vinegar if needed. I could make my own but often used Girard's - don't think made anymore. Keeps well and super for buffet events.
