Lunchbox ideas for snack

I need some lunchbox ideas/recipes for snacks.
I have got some apple mufins in the oven now and last week it was blueberry muffins. Now I am after something different to muffins.
Lots of ideas please and feel free to add recipes too ;)!!

Here is my apple muffin recipe
1 1/2 cups of self raising flour
1 tsp ground cinnamon (but we put in heaps cos we love it)
1 cup caster sugar
2 eggs lightly beaten
125g butter melted
2 apples cored and diced (but i use stewed apples probably a cup)
(the original recipe has a cup of sultanas too but we don't put them in)

It will make 12 muffins and I usually double the recipe when I cook them.

Preheat oven to 180oC and grease and dust muffin tin.
Sift flour and cinnanmon together, stir in sugar.
Combine eggs and butter together and stir into dry ingredients until just combined.
Fold in apples (and sultanans)
Spoon mixture into muffin tins and bake for around 20 - 30 mins depending on your oven.
