Trim fat from pork chops, and pound to 3/4 inch thickness. Season chops on both sides with Vege-sal or salt, pepper, and pork chop seasoning if using. Heat pan 1 minute, add olive oil, heat one minute more, then add pork chops and cook over medium high heat until well browned on both sides and cooked through, about 5 minutes total. Remove pork chops to plate, lower heat slightly, and add vinegar and sugar and cook until slightly thickened, about 2 minutes. Put pork chops back into pan with any liquid which has collected on plate, and cook about 4 minutes, turning several times to glaze pork chops with sauce. Serve hot, with sauce poured over.
