Portuguese cuisine is characterised by rich, filling and full-flavoured dishes and is a prime example of Mediterranean diet. The influence of Portugal's former colonial possessions is clear, especially in the wide variety of spices used. These include piri piri (small, fiery chilli peppers), as well as cinnamon, vanilla and saffron. There are also Arab and Moorish influences, especially in the south of the country. Olive oil is one of the bases of Portuguese cuisine both for cooking and flavouring meals. Garlic is widely used, as are herbs such as coriander and parsley.
