Cut your pork into bite size pieces. Place in a bowl with the apple juice and a pinch of salt and leave to marinate for 15 minutes. (You can leave it for longer if you want an even stronger flavour)
Dice the pepper, bamboo shoots and spring onion into small pieces.
Mix together the sauce ingredients in a bowl and set aside.
Beat an egg, and add it to your marinated pork, along with your 1 tbsp cornflour. Mix together. Then take each piece of pork and coat it in your plain flour as best you can. It doesn’t have to be perfect, but this will make your pork crispy!
Cover the base of a frying pan with a thin layer of oil. Heat until it is very hot, and then add the pork to cook. Stir, and cook for around 8-10 minutes until the pork is cooked through.
Lower the heat, add your vegetables and the sauce and keep stirring until the sauce thickens and goes sticky.
Serve with white rice or noodles and enjoy!
