Spray a 9x13 Baking Dish with non stick cooking spray.
Evenly place the potatoes and green beans in the dish then cover them with the olive oil, garlic, and rosemary.
Mix them around with a wooden spoon to get them well coated.
Place the pork chops on top of the veggies.
Lightly sprinkle the pork chops with the garlic salt. At this point you can also add additional rosemary to the pork chops. (If you would like to add the water or broth, you can at this point. I do not add it to mine because typically the pork chops I use have enough juice to them, but it will ensure that the veggies do not burn or dry out if you are concerned.)
Bake in the oven for 30 minutes at 400*, then carefully turn the pork chops and continue baking an additional 30 minutes until well done.
