Food on the Go

We are heading into a new homeschool year but that doesn't mean we are going to spend the year at home.  On the contrary!  What I love most about homeschool is the freedom to go out on adventures with  my children on a weekly basis.  Here we are at Greenfield Village with our friends.

In the past I would simply pack a pile of sandwiches, bag of apples and little baggies of other snacks but we are now restricted because of Henry's allergies.  I tried serving them cooked cauliflower and cooked beans out zip locked baggies but that didn't work too good.  So I picked up 3 of these Goodbyns as a means to store and serve our food on the go.  My sister Mary already blogged about the pros and cons here.  I'm still trying to figure out what to fill inside them.

Above I packed pears, bison sticks, dried bananas and raisins, cooked cauliflower and quinoa salad.  That is enough for two children.

Here are our restrictions:
-dairy
-eggs
-wheat/spelt
-oats
-millet
-nuts
-seeds
-anything processed in the same facility of nuts or seeds
-nightshade veggies (tomatoes, potatoes, peppers)
-citrus/acidic fruits

Basically Henry can eat meat and cooked veggies.  I tried packing different lunches for the other kids but the little piglet always seems to get into them.  At home we eat a lot of soup.......any ideas for what to pack for lunch?  Any ideas for breakfast, lunch and dinner at home?  I'm about to order one (or two) of these so we can have soup on the go but I'm wondering what others do for food on the go for a small crowd.
