Step 1Place quinoa and 1 cup of water in a saucepan and bring to boil. Reduce heat and simmer, covered, for 12–15 minutes, or until quinoa is al dente.
Step 2Meanwhile, heat half of the oil in a wok over high heat. Stir-fry mince for 2–3 minutes, or until browned. Transfer to a bowl.
Step 3Return wok to high heat; add remaining oil. Stir-fry chilli, garlic and lemongrass for 1 minute, or until fragrant. Add broccolini, carrot and capsicum, and stir-fry for 2 minutes, or until just tender.
Step 4Add quinoa, half of the bean sprouts and mince to the wok. Add hoisin sauce and stir-fry until heated through. Serve pork mixture in lettuce leaves topped with remaining bean sprouts.
