Put a baking sheet on the middle oven rack and preheat to 450 degrees F. Toss the Brussels sprouts and red onion in a large bowl with 1 tablespoon vegetable oil, 1/2 teaspoon salt and a few grinds of pepper. Spread on the hot baking sheet in a single layer and roast, without stirring, until tender and charred in spots, 20 to 25 minutes.
Meanwhile, whisk the vinegar, honey, Sriracha and a pinch of salt in a large bowl. Set aside.
Season the pork chops with salt and pepper and brush the mustard on both sides. Toss the panko with 1 tablespoon parsley, a pinch of salt and a few grinds of pepper on a plate. Press both sides of the pork chops in the mixture to evenly coat. Heat the remaining 1 tablespoon vegetable oil in a large nonstick skillet over medium-high heat. Add the pork chops and cook until browned and cooked through, 4 to 5 minutes per side. (Reduce the heat to medium if the crust gets too dark.)
Add the roasted vegetables to the honey-Sriracha sauce and toss to coat. Serve with the pork chops. Sprinkle with the remaining 1 tablespoon parsley.
