Yellow pepper and black bean stir fry

Method

1. If using the black beans, soak them in 250ml hot water for about 10 minutes, then drain and rinse thoroughly. Transfer to a pestle and mortar or a sturdy bowl and crush them roughly. Mix them (or the black bean sauce, if using) with the vinegar, honey and soy sauce, and set aside.
2. Put the oil in a wok or large frying pan over a high heat. When hot, add the peppers and stir-fry for a few minutes, until they just start to colour. Add the garlic, ginger and onions and stir-fry for a few more minutes, until the onions have softened a little.
3. Add the soy sauce and bean mixture to the wok and stir-fry for about 30 seconds. Check the seasoning, remove from the heat and serve, garnished with the coriander leaves.
