We try to do a healthy dinner the night before with a mix of carbs, protein, and veggies. If we’re traveling we always stay in a hotel that has a nice room service menu and do that the night before. We split an appetizer, salad, entree, and dessert so that we get to try lots of things and she gets a good variety. Oh, and we never have sushi the night before a meet just in case! After the meet, she chooses where we go for lunch or dinner.
Good luck to your daughter!
