For a richer flavor, consider using a combination of mushroom varieties, such as cremini or shiitake, in addition to white button mushrooms. If you don't have fresh parsley, you can substitute 1 tablespoon of dried parsley. Add it along with the garlic powder, salt, and pepper. Serve these pork chops with a side of mashed potatoes, rice pilaf, or buttered noodles to soak up the delicious sauce. A fresh green salad or roasted asparagus makes a perfect accompaniment. To ensure even cooking, use pork chops that are of uniform thickness. For best results, use a dry white wine. Avoid sweet wines.
