You need:
50 gr basil ( if you want to make it cheaper use 50 gr basil and 25 gr spinach instead)
a handful of grated cheese (ideally parmesan, but for a cheaper version use strong cheddar)
a handful of pine nuts
half a clove of garlic
olive oil ( 1 glass and a bit more to cover the sauce after it is ready)
Put all the ingredients in a blender and blend them well. That is all.
You can store this for a week and a half in the fridge covering the top of the sauce with some olive oil (around 1 cm) to prevent discolouring.
The children can do this on their own except that you need to supervise them while they use the blender.
