When I saw this recipe on delish.com I knew I had to try it. I fixed it for dinner with company and it was a hit. I doubled the recipe so I would have enough and I had very little leftover. One young man asked for the recipe, then said, "I don't usually like salads, so when I ask for the recipe, that's a compliment." It has a kick to it, but oh so flavorful.
Pick over shrimp, discarding any pieces of shell. Cover and keep chilled until ready to toss the salad.
Slice cabbage into chiffonade (very thin strips), about 1-2 inches long, to get 5 to 6 cups. Slice 12 cilantro sprigs very thin; reserve remaining sprigs for garnish. Keep everything chilled until ready to toss the salad.
Mix vinegar, peanut oil, fish sauce, chile sauce, sugar, and ginger in a small bowl. Keep at room temperature for up to 2 hours, or cover and refrigerate if making ahead; let cold dressing come to room temperature before tossing with the salad.
Just before serving, toss the shrimp, cabbage, sliced cilantro, carrot, and 6 tablespoons chopped peanuts with the dressing in a large bowl. Arrange lettuce leaves on a serving platter or in a large, shallow serving bowl. Mound the salad on the lettuce and garnish with the remaining 2 tablespoons peanuts and 8 cilantro sprigs.
