This loaded aubergine (eggplant) gyro is a succulent alternative to the traditional meat gyro. The eggplant absorbs the wonderful flavours of the paprika and oregano, and once cooked, it makes a colourful and fragrant stuffing for your pitta. Adding chickpeas and hummus to this dish is an excellent way to boost the fibre and protein content, and topping it with the cucumber and parsley makes for a refreshing finish.
