I've done it, but for me, "unlimited" doesn't add up to a lot of veggies when I can't dress them up with butter, cheese and/or sour cream. It was mainly avocados, tomatoes, mushrooms, peppers, onions, cabbage... things that I liked with bacon or into a stir-fry or coconut curry. I don't care for greens.

(ETA) Also condiment veggies like pickles and jarred salsa.
