This delicious salad illustrates the Tuscan flair for dishes with few ingredients, letting each ingredient deliver a lot of flavor. Porcini mushrooms are an autumn delicacy in Tuscany, and I ate my fair share when I visited, but you may substitute regular cremini (button) mushrooms instead.
In a medium serving bowl, toss mushrooms, parsley, oil, vinegar, and garlic together. Add sliced Parmesan cheese and toss lightly. Serve immediately.
