If you want crisps, why not make some of your own ? Parsnip, potato or carrots, sliced with a potato peeler, mixed with fry light and what ever flavouring you want! I make mine with hot paprika and no syns!
If you want a chocolate fix, make some chocolate truffles - 2.5 syns per 2, totally yummy and really simple to make :
50g dark chocolate chips
113g quark
2 options indulgence sachets (any flavour)
28g chocolate sprinkles
Melt the chocolate chips in the microwave for about a minute, then stir until smooth.
Beat the quark until creamy. Add the chocolate and mix well.
Add the options indulgence sachets and mix
Using a teaspoon, make 20 blobs onto some greaseproof paper and put in the fridge to harden slightly. (About 20 minutes).
Remove from the fridge, and roll into balls with the palms of your hands.
Roll truffles in the chocolate sprinkles and put back in the fridge to set overnight. Once set store in an airtight container in the fridge until ready to eat
Then fill up with the rest of your picnic with SF/F Foods, like carrot/cumcumber sticks, home made dip, easy fruit bite/kebabs (skewer strawberries, melon and kiwi)
Hope this helps!!
