There are lots of things I do weekly: a new batch of granola, a batch of muesli bars for the lunchbox, baby purées. This is another. 
Each week in my shopping I buy a 1 kg block of cheese or more. I cut the cheese up into small cubes. I keep half in a container for easy lunchbox items and I grate the other half in two batches. It’s so much cheaper to grate your own and there is no nasty additives or anti caking agents. 
The other plus to having cheese pre cubed is when you run out of grated you just need to grab a handful of pre cubed cheese and give it a quick blitz! Too easy.
