Napa Cabbage Picnic Salad

Napa cabbage (a kind of Chinese cabbage), while not as sturdy as regular cabbage, is much more resilient than lettuce, so it lends itself well to picnic salads that have to sit around for a while. This salad has Napa cabbage, radishes, snow peas, toasted slivered almonds, and a sweet sesame ginger mayo dressing. Much of it can be made ahead, and then assembled when you are ready to serve.
