Sprinkle the pork chops with salt & pepper and garlic powder, and then dredge them in flour.
Add 1 tbsp of the butter + the olive oil to a skillet over medium-high heat. Once the pan's hot, add the pork. Cook it for 3-4 minutes/side or until it has a nice golden crust.
Meanwhile, chop the apple.
Take the pork chops out and set aside.
Add the Dijon mustard, chicken broth, and the rest of the butter. Give it a good stir until the mustard dissolves.
Add the apples and Italian seasoning and let the sauce cook for a few minutes.
Add the pork back into the skillet. Reduce the heat to medium-low, cover the pan, and cook for 2-3 minutes or until the pork is cooked through (145F - it's ok if it's a bit pink!).
Take the lid off the pan, and if the sauce is reduced to your liking and the apples and pork are done, serve. If not, continue cooking for a little longer (leave the lid off to reduce sauce).
