Pork Chops with Vinegar & Peppers

This recipe is substantially de-convoluted from the Cook's Illustrated version. The original called for browning the chops on the stove, then finishing the whole dish in the oven.  However, this easily adds 20 minutes to the cooking time.  It's much more practical on a weeknight to pre-cook the chops fully, then bring them back together with the peppers at the end.
