In this novel take on a side salad, carrots, snow peas, radishes, and mint are served bundled up in a lettuce leaf. We cut the carrots and radishes into fine strips on a mandoline; you can also shred them on the large holes of a box grater.
In a medium bowl, combine carrots, radishes, pea shoots, and mint. Add vinegar; season with salt and pepper. Toss gently to coat.
Place a small handful of vegetable filling on a lettuce leaf. Fold sides over filling, and roll up to make a bundle. Repeat with remaining ingredients. Serve chilled or at room temperature.
