This fresh salad contrasts the subtle flavor of butterhead lettuce with the piquant taste of radish and the sweet flavor of carrots. The season's first sprouts add an earthy dimension to this simple dish.
In a large bowl, whisk together vinegar and oil; season with salt and pepper.
Tear lettuce into bite-size pieces and add to bowl along with radishes and carrots. Toss; season with salt and pepper.
Divide salad equally among four plates and top each with sprouts. Serve immediately.
