I found this recipe on the Coles iPhone app & we're going to make them tomorrow. I figure they'll be good to go with preschool lunches.

Ingredients:
150gm butter at room temperature
1 1/2 cups flour
1 cup grated cheese
1 bunch chives, snipped

Method:
1. Using a wooden spoon, beat butter until creamy. Add remaining ingredients & mix until just coming together.
2. Turn out onto a lightly floured board & knead dough until it forms a smooth ball. Divide in half. Roll each piece into a 15cm log. Wrap in non stick baking paper & chill for 30 minutes.
3. Preheat oven to 180degrees. Line 2 baking trays with baking paper. Cut 20 x 8mm slices from each log. Place on trays.
4. Bake for 12-15 minutes until firm. Cool on trays. Store in airtight containers.
