Bring a medium saucepan of water to the boil for the noodles. Thinly slice the onion. Trim the beans, then halve lengthwise (see Make it faster). Shred the carrot using a julienne peeler or coarsely grate with a box grater. Crush or finely chop 2 garlic cloves.
Step 2 — Cook noodles
Cook the noodles in the pan of boiling water for 2 mins or until tender. Drain, then rinse under hot water to prevent the noodles from sticking. Combine half the Chinese barbecue seasoning, 1½ tbs soy sauce, 1 tsp honey and 1 tbs water in a bowl.
Step 3 — Brown lamb mince
Heat 2 tsp vegetable oil in a medium deep frypan over high heat. Cook the lamb mince and garlic, breaking up the lumps with a spoon, for 3-4 mins until browned. Remove from the pan with a slotted spoon. Reduce the heat to medium and cook the onion, stirring, for 3-4 mins until softened.
Step 4 — Add veggies
Increase the heat to medium-high, add the beans and carrot to the onion and stir-fry for 1-2 mins until the beans are tender but still with crunch. Add the mince and remaining Chinese barbecue seasoning and stir-fry for 30 secs or until fragrant. Add the noodles and sauce mixture and stir-fry for 1-2 mins until combined. Remove the pan from the heat.
Step 5 — Serve up
Divide the lamb and veggie noodles among bowls and enjoy!
Step 6 — Make it faster
Halving the beans lengthwise looks pretty, but if you're short on time simply cut them into short lengths instead.
