The salad greens are well underway. If a severe frost/freeze comes up in the next few weeks, I'll toss some Remay row cover fabric over them - and I do expect that freeze to occur, as it does so almost every year.
But that's only the start of it. For a startlingly beautiful salad, I always plant several of the multicolored lettuce varieties and the engaging, frilly looseleafs. Now that's something you seldom, if ever, see in a supermarket. Tedious to clean garden dirt out of (mulch well with straw or paper!!) but wonderful. One of the most adaptable romaine types is also the most striking - Forellenschuss. (see photo below)
