I sometimes make pasties for my children's lunchboxes.  Their favourite fillings are:

1 tin tuna mixed with chopped spring onions, black pepper and 1 tablespoon mayonnaise or plain yoghurt

diced bacon, dry fried, add 1 tablespoon plain flour to the pan, milk to make a sauce, and mixed veg (frozen is fine if you prefer)

If made with ready made plain pastry, roll the pastry out really thinly (I try to get it thin enough to see the pattern on my plastic tablecloth ), cut into circles, and put 1 teaspoon of filling in the middle. Fold over and seal, using water or milk, place on a tray in a hot oven for about 15 minutes (or until golden brown).  I make really tiny ones, and make a variety of fillings - that way you can get a lot of pasties from one pack of shortcrust pastry.  I often use stewed fruit as a filling as well. If you give a variety of differently filled pasties, it can add an element of surprise!

Another favourite is a flask of vegetable soup, or my youngest likes to take in a flask of risotto.

Here's a couple of other ideas!

I make vegetable "crisps" from time to time, using a potato peeler or a cheese slice to get thin strips.  It's easy with carrots, parsnips, potatoes, beetroot and sweet potato - you just shave some slices, spray some oil over and put them in the oven until they're crispy - really yummy (and for the grown-ups, too ).  My eldest likes cherry tomatoes stuffed with cream cheese, garlic and herb substitute (it's made from soya, as we're all lactose intolerant), and I sometimes make a hummous with added avocado for a dip to go with fresh vegetable sticks.

I don't know if it's authentic hummous - I read a recipe ages ago in a magazine, and did what I remembered  but it tastes good!

1 small can chickpeas, drained
1 clove garlic
salt & pepper to taste
lemon juice, about 1 teaspoon
1 tablespoon plain yoghurt
flesh of one ripe avocado

Put it all in a blender and whizz until smooth.  Serve on pitta bread, or as a dip with veg sticks.

I sometimes experiment adding different flavours or spices, (cayenne pepper's quite good if you like a kick), but that's my basic recipe.  It's quite mild, so children seem to like it, and I've used it as a sandwich filling as well.

Good luck!

That's OK - pulses are so full of vitamins and minerals, that I like to sneak them into as many dishes as I can without the children knowing!!  Hope it works well for you
