Cut the pork crosswise into 16 pieces.
Sprinkle evenly with salt and pepper.
Place pork in pan; cook 4 minutes on each side or until golden brown.
Remove pork from pan. Stir in wine mixture, scraping to loosen browned bits. Increase heat to high; bring to a boil. Cook until reduced to 1/2 cup (about 3 minutes).
