I'm a big fan of quick easy recipies which don't create too many dishes.
I use this one alot for school lunch snacks.
1 cup flour
1 cup toasted sesame seeds (or chopped walnuts or pumpkin seeds)
3/4 cup brown sugar
1 tsp vinilla essence
1/4 tsp baking powder
Cream butter and sugar. Add egg and essence, beat well. Mix in rest of ingredients. Place in teaspoonfuls onto a tray and flatten with a fork. Bake at 180 C for 10 mins.
