Heat a large wok over high heat until very hot. Add 1 teaspoon of the oil and swirl to coat the wok. Add one third of the beef and stir-fry for about 30 seconds, or until just sealed. Remove to a plate. Repeat with remaining beef in two batches.
Add remaining oil with the Broccolini® and Sugar Snap Peas. Stir-fry for 1 minute. Add 2 tsp of water, cover with a lid and cook, shaking the wok often for 45 seconds or until bright green.
Remove the cover and add the stir-fry sauce and noodles. Bring to the boil, stirring often. Return the beef to the wok and stir-fry until combined. Serve.
