Preheat the oven to 450 degrees F. Place mushrooms and 1/4 tablespoon olive oil in a bowl.
Sprinkle w/ salt and pepper and oregano and toss to distribute oil and seasonings. Turn out into a rimmed baking sheet and set aside.
Toss asparagus in remaining olive oil. Season with salt and pepper, place asparagus on another baking sheet.
Place both baking sheets in oven and roast until asparagus is tender (10-15 minutes depending on thickness) and mushrooms are tender and golden (approximately 20 minutes).
Remove from oven and arrange on platter. Serve hot or at room temperature.
Mushrooms will bring out the earthy characteristics in Zinfandel. You can substitute shiitake or other wild mushrooms for the cremini mushrooms.
