Personally, I find it most satisfying to eat foods that are primal by nature, rather than trying to construct primal versions of non-primal foods, like pasta or pizza.
There are a lot of ideas for kids' lunches on this forum. Things like:
- Deli meat wrapped around cheese or avocado slices
- Container of olives to eat with a toothpick
- Primal trail mix
- Cold chicken drumsticks
- Greek yogurt with primal granola (no grain, obviously) and berries
