FOR BREAKFAST I have a plain egg-white omelet (three eggs) and bottled water. For lunch, a piece of grilled or seared fish with white rice or a bowl of chicken-and-rice soup. And water. I drink water all day long, during the season and when I'm training. For dinner I want real sushi--not the Americanized kind. My parents are American Samoan so I don't go for any of those rolls. I'll have raw prawn or sea urchin or octopus. I love it. Fortunately enough places in Miami and San Diego have that stuff on the menu to keep me satisfied. My favorite treat? A vanilla, soft-serve ice cream in a plain cone. Pure and simple.
