Summer is here! And while we pack away our winter clothes and our electric blankets, it's also time to rethink our weekly meals and what to make to replace those hearty dishes, such as oxtails, stews and curries, that are so satisfying and comforting in the colder months.   Summer also means spending as much time outdoors as possible, and who wants to slave in the kitchen for hours while friends and family are outside splashing around in the pool or enjoying sundowners.
