My kids have two lunch boxes. One is for cold lunches like sandwiches and another one for hot with a thermos food jar. I find that I pack hot lunches most of the time. I do raviolis, pasta with butter, pasta with cheese, homemade chicken nuggets, spaghetti and meatballs, dinner leftovers, soups, etc etc. To me, a thermos food jar opened so many more possibilities! So, lately it's been a hot item, a raw fruit and a raw veggie and a snack (crackers, pretzels, cheese sticks, squeezable organic yogurt). I can send you the links to the lunch gear we have if that would help! I also love 100 days of real food blog and she has a school lunch section too. Good luck!
