1 (10.75 ounce) can condensed cream of mushroom soup
Season pork chops with salt, pepper, and garlic salt to taste.
In a large skillet, brown the chops over medium-high heat. Add the onion and mushrooms, and saute for one minute. Pour cream of mushroom soup over chops. Cover skillet, and reduce temperature to medium-low. Simmer 20 to 30 minutes, or until chops are cooked through.
