Add olive oil to a large skillet over medium- high heat. Salt and pepper both sides of the pork chops and place in skillet.
Cook on each side for 4-5 minutes, until cooked through and golden brown on the outside. Remove pork chops from the skillet and set aside on a plate.
Add mushrooms to the same skillet and sauté for 2-3 minutes, or until tender, then set aside with pork chops.
Melt butter in skillet and whisk in flour. Cook for 3-4 minutes, or until lightly brown. Whisk in beef broth, milk and Worcestershire sauce and bring to a simmer until sauce starts to thicken. Season with salt and pepper, to taste.
Add pork chops and mushrooms back to the skillet and let simmer for 2-3 minutes. Serve over mashed potatoes, if desired (not included in nutrition information).
