Marinate morels in olive oil and lemon and orange zest for at least 4 hours.
For the Salad: Shave pecorino into 1/8-inch slices that measure 1 1/2 inches long by 1/2-inch wide. Set aside. Shuck and peel fava beans. Cook in boiling water with salt until they are tender.

For the Vinaigrette: Mix olive oil, red wine vinegar, lemon zest and orange zest. Season with salt and pepper. Stir in beans.
Place morels and cheese slices decoratively on a clean plate. Dress with vinaigrette. Top with thin slices of summer truffles. Serve.
