Preheat an oven to 375 F. Line a sheet pan with aluminum foil and place in the oven.
Season both sides of each pork chop with salt and pepper.
4 boneless pork chops (about 3/4" thick), 2 teaspoons kosher salt, ½ teaspoon ground black pepper
In a large skillet over medium high heat, heat the vegetable oil until hot and it begins to shimmer.
3 tablespoons vegetable oil
Add the pork chops and cook for about 4 minutes per side until they start to brown. Remove from the skillet and place on the pan inside the oven. Bake for 8 to 10 minutes or until they reach an internal temperature of 145 F.
In a small bowl, whisk together the brown sugar, vinegar, ketchup, soy sauce and ginger, set aside.
⅓ cup brown sugar, ½ cup rice vinegar, 3 tablespoons ketchup, 2 tablespoons soy sauce, ½ teaspoon ground ginger
In the same skillet used to sear the pork chops, saute the garlic, bell pepper and onion over medium heat until they begin to soften, about 4 minutes.
2 cloves garlic, minced, 1 red bell pepper, seeded and cut into 1 inch pieces, 1 green bell pepper, seeded and cut into 1 inch pieces, ½ white onion, thinly sliced
Add the vinegar sauce to the pan and bring to a simmer.
In a small bowl, use a fork to mix the cornstarch and water into a slurry. Add to the sauce and return to a simmer. Cook on low while stirring until it has thickened slightly, 3 to 4 minutes.
1 tablespoon cornstarch, 2 tablespoons water
Spoon the sauce over the pork chops to serve.
