Hand-pulled noodles are topped with a hearty stir-fry of lamb, tomatoes, peppers, and onions in this Uyghur staple. High in protein and packed with fresh vegetables, this family dish reflects the bold flavors of China's northwest.
Mix all-purpose flour and 1 cup water in a bowl until a dough forms. Knead for 10 minutes until smooth, cover with plastic wrap, and let rest for 1 hour.
Slice lamb shoulder into bite-size strips. Dice onion, potatoes, and bell peppers; slice tomatoes; mince garlic.
Divide rested dough into 8 pieces. Roll each into a log, cover, and let rest 15 more minutes. Meanwhile, heat 2 tbsp oil in a large wok over medium-high heat.
Add lamb strips and sauté for 2–3 minutes until browned but still tender. Remove and set aside.
Add remaining oil, onion, garlic, and potato to wok. Stir-fry for 3 minutes, then add bell peppers and tomatoes; cook another 5 minutes, adding soy sauce, cumin, salt, and pepper. Return lamb to wok and simmer on medium-low while you pull noodles.
Coat your hands with oil; stretch each dough log into a long, thin noodle by gently pulling and bouncing on the work surface. Boil stretched noodles in a large pot of salted water for 2–3 minutes until al dente. Drain well.
Divide boiled noodles among bowls. Spoon hot lamb and vegetable stir-fry over noodles. Serve immediately.
