Preheat oven to 450°. Spray a baking sheet with cooking spray. Put the mushrooms and asparagus in a bowl and drizzle with olive oil. Season with the spices. Stir to coat it all. Lay mixture on baking sheet evenly. Put butter chunks scattered over the mixture. Roast for 10 minutes, check to make sure asparagus is tender. If not, then roast 2 more minutes. Be careful not to overcook the asparagus.
