Pre-heat the oven to 190-200°C.
Season the strips of beef, then dip each one into the beaten egg, then quickly drag it through the flour to give a light coating.
Place each piece of coated beef on a baking tray sprayed with a fair bit of low calorie cooking spray, then give the strips a spray too. You could even put it on a piece of baking parchment to ensure it doesn't stick.
Cook for 20-25 minutes, until the beef is crispy. You can turn it over towards the end if needed.
While the beef is cooking, spray a wok with some low calorie cooking spray. Then over a medium/hot heat, fry the peppers, carrots, onion, spring onion, chilli flakes, garlic and ginger.
Cook for 5 minutes, then add the lime juice, granulated sweetener, soy sauce, rice vinegar and honey.
Stir, then add a couple of drops of Franks sauce and the 100ml of beef stock.
Allow to cook for a minute and then add the cooked beef strips.
Stir well and serve with your choice of accompaniment.
