Tender chicken tops a crisp pancake for a dinner that's better than takeout, and just as fast.
1. Preheat oven to 200°. Boil noodles according to package instructions. Drain. Heat 1 tbsp. each vegetable oil and sesame oil in a medium nonstick frying pan over medium-high heat. Spread noodles evenly in pan and cook, turning once, until browned and crisp, about 5 minutes per side. Keep warm in oven.
2. Meanwhile, cut chicken into thin strips. Season chicken with salt and pepper and set aside. Trim bases of bok choy and separate leaves; if longer than 3 in., cut in half crosswise. Rinse and thoroughly dry bok choy in a salad spinner. Combine oyster sauce, soy sauce, and 2 tsp. sesame oil in a small bowl; set aside.
3. Heat a wok or large sauté pan (not nonstick) over medium-high heat until hot when you wave your hand over the bottom. Add remaining 1 tbsp. each vegetable and sesame oil, the chiles, garlic, and ginger and cook, stirring, until fragrant, 10 seconds. Add chicken and sausage and stir-fry until chicken is no longer pink, 1 to 1 1/2 minutes. Add bok choy and cook, tossing with tongs, until beginning to wilt, 1 minute. Add oyster-soy mixture and cook until sauce boils, 30 to 45 seconds. Slide pancake onto a cutting board and top with stir-fry. Serve immediately.
