try mark's banana almond butter pancakes - delicious! We're in the same situation - lunches are tricky, but I use gluten-free biscuits and bars where possible (a small step in a better direction) and they have a box of salad, an ice brick keeps it cool. No meat though, I want real cold for that in this weather.
I think it's worthwhile to consider your key issues and work on them first. With eczema I seem to remember wheat gluten is an issue though I might be wrong. For some people with diabetes in the family, dropping sugar might be a bigger issue.
My approach has been trying to introduce little bits of more primal foods (hard because they had very bad, bland eating habits before) for example adding a topping of coconut flakes and nuts to cereals, a bit of coconut milk in the smoothies. I've tried using some fine dessicated coconut in oatmeal, I like it (I use half and half rice porridge plus coconut) myself but my kids aren't fond of it. (if you try it, use extra liquid).
school lunches are so frustrating, anything prepackaged is full of either sugar or salt.
If we’re not supposed to eat animals, how come they’re made out of meat? Tom Snyder
