S.S.
Have you tried edamame? My son loves it -- either shelled or unshelled. Also, I pack all kinds of berries and fruit (cut up) to make it easier to eat. Another fool proof item is raisin bread with whipped cream cheese and fruit. And lastly, he also loves cucumber sandwiches (really - whipped cream cheese and slices of cukes, I leave the crust on b/c that is where most of the nutrition is). I also do soup in a thermos. Good luck...
