Yeah - I echo the above. Eat what you are comfortable with, and can digest quickly. For my first meet I got advice from candy bars and crap, all the way to ground lamb - both of which could have made me feel crummy.
The key I think is a good dinner the night before, a good breakfast, and lots of fluids. Then during the day eat small amounts along of whatever usually fuels your workouts.
You didn't say if you have to cut water out to make weight? If so, be sure to replace your electrolytes with Gatorade or Pedialyte.
