This is a salad of greens, topped with warm mushrooms and an herb-based vinaigrette.
Heat oven to 350 degrees. Arrange mushrooms on piece of foil; season with wine, 3 tablespoons oil, salt, and pinch of pepper. Slice 1 clove garlic; scatter over mushrooms. Fold foil to create loose package. Bake until mushrooms are fork tender, 15 to 20 minutes. Transfer to large bowl.
Finely chop remaining garlic clove; add to bowl along with pecorino and chopped herbs. Toss, and season to taste with salt and pepper.
Place greens in a bowl; season with remaining oil, salt, pepper, and vinegar. Arrange greens on serving plates, and top with warm mushroom mixture. Garnish with shavings of pecorino if desired.
Classic pistou (not pesto, no pine nuts here) is a mixture of crushed basil, garlic, and olive oil, but almost any other herb, such as parsley, thyme, or oregano, can be used in place of the basil.
