Indeed the versatile tomato could almost be seen historically as a calling card from the Portuguese. In Brazil one can eat Moquecas which are a spicy tomato-based stew which sometimes resemble the the spicy fish curries in the South of India.

And in Portugal itself Refogado is tomato sauce that forms the basis of many wonderful stews, soups and rice dishes there.
