Planning a birthday picnic (for grandparents, parents and grandchild aged 8):
Ideas please for homemade picnic food that's special for a birthday! Must be vegetarian / pescetarian, and travel ok in a backpack. Climate will be UK springtime so no worries about things getting too warm.
What matters: making it feel special for my mum in lieu of regular birthday presents.
Vegetarian or pescetarian.
Portable- we're having a walk too.
