Summer vegetables?

Summer vegetables?

What are some quick growing summer vegetables that you can grow? I've already got radishes, beans, squashes, lettuce, corn, peppers, tomatoes, eggplants, and turnips. I'm starting to get empty beds as I harvest vegetables and I'm stumped as to what to do with the beds besides find something that isn't growing and plant it. Is there lettuce that can survive the summer heat?
