V.S.
Just wanted to add a few more things to the list. My 4 year old likes:
Sandwiches = avocado, tomato, cheese, mustard on pita or flax seed bread, cream cheese & jelly, almond butter, egg salad on flat bread with green leaf lettuce and tomato.
In a thermos - Pasta with olive oil & pine nuts (served cold is good too) or spinach pasta with feta, warm rice with butter, spinach lasagna, homemade mac & cheese
Celery sticks with almond butter and raisins, trail mix, rice cakes, pita bread/carrots with hummus
