For a light freeze, all the coles and mustards, lettuce, carrots, spinach

Also, peas (English peas, snow peas, sugar snap peas), parsnips, parsley, and alliums (onions/garlic/chives/leeks/shallots) will survive light freezes. Some perennial herbs like thyme and rosemary will remain green through light freezes, too.

Actually, pansy flowers are edible, and they survive light freezes. That counts, right? :-)

I agree with all but the statement about peas. Young pea plants will survive light freezes, but as they mature, and especially when setting pods, they become much more susceptible to frosts.
