| dish: salad|
Preheat oven to 450 degrees, with racks in upper and lower thirds. On a rimmed baking sheet, toss mushrooms with 1 tablespoon oil; season with salt and pepper. On another rimmed baking sheet, toss potatoes with 1 tablespoon oil; season with salt and pepper. Roast until mushrooms are browned and potatoes are cooked through, about 20 minutes, tossing once and rotating sheets halfway through. Transfer to a bowl and toss vinegar, and capers, if desired.
