In a large skillet over medium high heat, heat oil until just smoking.
Place pork chops in a single layer and brown on both sides. Remove and set aside.
Add vegetables to the pan and saute until starting to brown, about 3 minutes. Set aside with the pork chops.
Add balsamic vinegar and beef broth, scraping the bottom of the pan.
Add salt and pepper.
Bring to a boil and add the pork chops and vegetables back into the pan.
Simmer on medium low for about 5-7 minutes, until the sauce has reduced and thickened and the pork chops are cooked through (165 degrees F), (see note).
Add the cold butter into the pan, tossing the vegetables and meat gently to combine it with the sauce.
Sprinkle with fresh parsley and basil.
Regular balsamic can be used, or you can substitute in a flavored balsamic like honey balsamic. If you are unsure how potent your balsamic vinegar is, add 1 tablespoon, taste, and adjust from there. I find different brands of balsamic vinegar vary greatly in taste and potency.If your liquid starts to evaporate too quickly but the pork chops are not cooked through yet, add more beef broth to the pan.
