In a skillet over medium-high heat, sear pork chops for 2-3 minutes on each side, just until slightly browned.
Transfer pork chops to a baking dish (make sure they're touching and not too spread out).
In a small bowl, whisk together maple syrup, water, minced onions, vinegar, Worcestershire sauce, chili powder, and salt and pepper. Pour over pork chops.
