I need some ideas please for kids school lunches.. we are vegetarian can have eggs and dairy, no fish or meat. I usually do sandwiches need some inspiration. I need more protein ideas please. Would an omelette wrap work well? Any tips on ensuring the wrap doesnt go soggy? How would you store it in the lunchbox.. any other ideas please? I can't use peanut butter as it is a nut free school. Sandwich filler ideas also welcome. Tia
