Season the pork chops with the five-spice powder and grill seasoning. In a large nonstick skillet, heat 2 tablespoons oil over medium-high heat. Add the chops and cook for 6 minutes on each side. Add 1/4 cup hoisin sauce, turning the chops to coat. Keep warm.
In another large skillet, heat the remaining 2 tablespoons oil over medium-high heat. Add the bell pepper and garlic and cook for 2 minutes. Add the corn, snow peas and scallions and cook for 3 minutes. Stir in the remaining 1/4 cup hoisin sauce and the hot sauce. Serve alongside the chops.
