Heat peanut oil in a large skillet over medium-high heat. Season both sides of the pork with salt and black pepper. Add pork to the skillet and cook 2 minutes per side, until golden brown.
In a medium bowl, add the cornstarch, brown sugar, broth, soy sauce, and sesame oil. Mix well. Using a spoon, combine the orange marmalade. Mix well and add to the pork in the pan. Bring to a simmer for 5 minutes, or until pork is cooked through and the sauce thickens and reduces. Arrange noodles on a serving platter. Top with pork chops and sauce. Garnish with scallions/green onions and sesame seeds.
