Radish and Pea Salad

I just call this "Christmas Salad" because of the colors Chop up fresh snow peas (can blanch or microwave for a minute or two to soften if they're really large), radishes, and 2-3 scallions (white & green parts). Whisk together 1/4 c rice vinegar, 2 tsp sugar (or substitute) and 1 Tb olive oil, then pour over and refrigerate a couple hours for best flavor

(I believe I found this recipe in an Ellie Krieger cookbook)
