Divide the pork, prunes, peppers and water chestnuts into two batches. Thread them alternately onto bamboo skewers and place in a high sided plate.
Mix the honey with the soy sauce. Pour over the skewers and marinate for at least ten minutes.
Heat a frying pan, add a tablespoon of olive oil and cook the skewers for eight to ten minutes, turning so that they are evenly coloured on all sides and cooked throughout.
Transfer to a dish and serve warm.
