Cook the noodles following the pack instructions, then drain and cover to keep them warm.

At the same time, spray a non-stick wok or large frying pan with low-calorie cooking spray and put it over a high heat. Working in batches, stir-fry the beef for 1-2 minutes or until browned, then tip into a bowl and cover to keep warm.

Spray the wok with more low-calorie cooking spray and stir-fry the garlic and chilli flakes for 1 minute. Stir in the paprika, passata, soy sauce and sweetener and cook until heated through. Return the beef to the wok and keep warm over a low heat.

Spray another non-stick wok or large frying pan with low-calorie cooking spray and stir-fry the veg over a high heat for 5 minutes or until tender.

Divide the noodles, veg and beef between shallow bowls and spoon over any sauce left in the wok to serve.
