Off to IoW for a week tomorrow and am ordering an online shop to be delivered to our accommodation. Money is tight, so we plan on picnicking most days. I just can't face a whole week of pb sandwiches on my holiday (our normal picnic standby).
Any super easy ideas I can steal without racking up the cost with poncey breads/cheeses/balsamic pearls? 
For two adults, a fussy beige food fanatic 3 year old and a wee but so far gastronomically adventurous baby of 8 months?
