Fresh fava beans join baby spinach, frisee, and mint in a delicate salad accented by goat cheese.
Prepare an ice-water bath. Bring a medium pot of salted water to a boil. Add fava beans, and cook until tender, about 1 minute. Using a slotted spoon, transfer beans to ice-water bath. Drain, and squeeze beans from skin.
Toss beans, frisee, spinach, mint, carrot, and shallot in a large bowl. Dot with tablespoons of goat cheese.
Place vinegar in a small bowl. Add oil in a slow, steady stream, whisking until emulsified. Season with salt and pepper. Drizzle dressing over salad, and toss to coat. Serve immediately.
