That's packed lunch for a 3 yr old, not a packed lunch I made in 2003.
I'm going to be sending my 3 yr old to lunch club after his morning preschool session once a week (recommended to help his social skills). I don't think he'll be really pleased to go so would like to put some special things in his lunch box. It also needs to be easy to eat (so he can get the food in) and healthy (mainly to please me) but sufficiently tempting he doesn't raid other kids lunches. High staff to kid ratio, so I'm sure they can help with packets etc. Needs to be fairly clean to eat, though.
I've thought of .... Baby Bels (v popular), cooked cocktail sausages (I think they are evil - but they are popular), pasta salad?, cherry toms / cucumber, ...
