Well it is almost winter... even in zone 7 where you probably are, it's kind of limited for vegetables. Depending on when your frost date is, you might be able to get some radish or arugula or spinach in yet. You can plant garlic, leeks, and onion sets now to overwinter for spring. You could plant artichoke roots now also to overwinter. It's probably a little late for starting broccoli from seed, but if you can get broccoli plants, they will probably do all right, especially if you can give them some cover for frosts (like cloche or cold frame).
Otherwise spend your time getting everything ready for next year, clean up and mulch all your beds, prune things. Especially where you are, it's still a good time to plant trees and shrubs. I start seeds under lights in my basement starting in mid January... gives me my gardening fix in the depths of winter
