Pork Maitake Asparagus Stir Fry

I always hear that maitake mushrooms go well with pork, so today I stir fried them together along with some asparagus and onions. I regularly buy shiitake and shimeji mushrooms, but hardly ever buy maitake. Some interesting discoveries from the package: their English name is "Hen of the Woods," and apparently they're pretty wonderful in terms of the richness of minerals and vitamins they provide - a small pack of them contains 312% daily value of Vitamin D! They're pretty tasty too, with a more distinctive look/texture than shimeji mushrooms.
