Spring is the season for fresh fava beans -- tan flat beans that resemble limas, though not as starchy. Pino Luongo, of Coco Pazzo in NYC, tosses favas with baby greens and fresh Pecorino cheese.
Bring a large pot of salted water to a boil. Prepare an ice-water bath. Add favas to boiling water, and blanch 1 minute. Using a slotted spoon, transfer to ice bath to stop cooking; drain. Peel and discard tough skins; set aside.
In a small bowl, combine shallots, lemon juice, salt, and pepper. Slowly whisk in olive oil until emulsified.
Arrange lettuce and watercress on a platter. Top with fava beans. Drizzle with vinaigrette, and sprinkle with cheese.
