Add the red pepper, courgettes and beans. Dissolve the marmite in the boiling water and mix with the sugar and tomato puree. Pour into the dish. Add the chopped dates.
Cover and cook for 10 minutes on 100% full power; then stir, cover and cook for a further 20-30 minutes on 50% power until the sauce is thickened and the beans are cooked through.
Season to taste with the salt and pepper. Mix together the coriander/parsley and orange zest and scatter over the dish just before serving.
