500g/1lb chicken breast, cut into 2.5cm/1in pieces
1 red pepper, deseeded and cut into chunks
1 zucchini diced
3 tbsp mirin
3 tbsp Japanese soy sauce
3 tbsp sake (rice wine)
1 tsp sugar
Thread the chicken pieces onto pre-soaked bamboo skewers, interspersing each piece of chicken with pepper and zucchini.
Mix together the mirin, soy, rice wine and sugar and stir until the sugar dissolves.
Heat a griddle pan and brush the chicken with the glaze. Griddle turning every 30 seconds or so, brushing the top each time until the chicken is cooked through and the meat burnished a to mahogany glaze.
