Make the fried rice: In a wok, heat oil or butter. Sauté garlic and ginger until fragrant (do not brown). Add corn, peas, carrots, bell peppers, and pork. Season with salt and pepper. Sauté until carrots are cooked through. Add rice; mix well. Pour in remaining cooked marinade. Season with more salt and pepper, if needed. Sprinkle with green onions.
