A Chinese take-away classic on your table in less time than it would take for the delivery driver to find your front door. The cornflour coating on the chicken is what makes it super tender. Don't skip this stage. Also great with beef, pork or just loads of veg.
Based on 4 servings, adjust as needed.
Cut the chicken into 3cm pieces and place into a bowl along with the cornflour, soy sauce and a splash of water. Leave to marinade for 10-15 minutes while you cut up peppers, onion and spring onions (keep the white and green parts separate). You can also mince the garlic, slice the chilli and cut the ginger into very thin matchsticks.
Heat half of the sesame seed oil in a large wok or high-sided frying pan. Turn the heat to high and once nearly smoking, add the marinaded chicken. Stand back as it may spilt. Move the chicken around the wok until it's golden all over and nearly cooked through. About 6-8 minutes.
Remove the cooked chicken from the pan using a slotted spoon and place to one side in a bowl. Add the reaming oil to the pan and add the garlic, ginger, and chilli. Cook for 1 minute, while continuing to move the aromatics around in the oil. Now add the diced peppers, whites of the spring onions and white onion. Coat well in the infused oil.
Add 4-6 tbsp of water (if cooking for 4) to the pan and allow the vegetables to steam slightly for 4-5 minutes. Add the chicken back into the pan before pouring over the black bean sauce. Bring to a simmer and coat everything well in the sauce. Allow to cook for 2 minutes while you heat the rice according to the packet instructions.
Scatter the green tops of the remaining spring onions into the stir fry before serving while pipping hot along side the rice.
