hi G.. i pack my daughter's lunch everyday, she is going into the 1st grade. i love to pack her lunch because i feel like i send a little part of me with her to school plus i know she gets healthy servings of 'most' of the food groups. i purchased, at wal-mart, a lunch set from rubbermaid. there is a sandwich box and several other smaller containers that fit neatly into her insulated lunch carrier. here is the basic list of things i send with her, any combination works.
1. bread~~ritz or club crackers (6), pretzels, goldfish crackers, bread, occassionally cheetos or doritos.
2. meat~~sliced ham, turkey, drained tuna plain, cottage cheese, string cheese, peanut butter, grilled chicken.
3. fruit~~she doesn't eat vegies, something we are working on, i love the little fruit cups too, also peeled and sliced apples, grapes, i don't put bananas in there, they get yucky too quickly. and applesauce cups work well.
then she gets milk served by the school.
in my experience with her, she eats 'prepared' food much better, meaning, she would do the same with the lunchable, but if i slice and dice everything she seems to eat more. i even open and drain the fruit cups and put them in one of the little containers otherwise the cups come home unopened. plus lunchables are expensive.
i hope this helps, it seems pretty simple when her lunch contains pretzels, a cheese stick, and cup of mandarin oranges, but that is an appropriate meal for a child her age and sustains her until she gets home. if only i could feed myself as well...lol....best of luck....get the containers, they have latches that click down on all 4 sides and never leak, even when i send tuna, she loves it!
don't forget little love notes sometimes and i put a sweet treat such as a few m&m's or a mini kit kat in there, not everyday, just for a treat, i told her the fruit is dessert :-)
