To assemble lunches get items from all 5 categories, plus a selection of small containers (ikea,have a huge selection)
get the kids involved chopping the
veg, fruit, cheese and proteins, also making the yogurt and dressing.
I recommend buying a large tub of natural yogurt from Lidl its approx .a euro. mash some berries and divide into small containers. You can make enough for a week in keep the containers in the fridge. Its a cheap and healthy solution.
If children like sandwiches the wraps or pittas can be filled with a protein some salad and veg of their choice. For those not interested in sambos give them some yogurt some veg chopped up in a tub some cheese or meat maybe a dip and a treat. Lunches don't have to be boring
