Grilled Pineapple Mojitos

The World Cup begins today, so its a good time to start thinking about what you will sip on while you watch some of the world's most attractive males kick a ball around a field. I nominate the mojito: always a delicious drink, but especially refreshing in the summer. Since Brazil is hosting this year, why not make it your goal (heh) to kick your mojito up a notch by including one of Brazil's most popular exports: the pineapple?
