Auditor's Fridge

I'm getting used to shopping and cooking for myself again, but with the cost of food so expensive here in Switzerland, am trying to be strict and organized on what I have in the fridge!

the thumbnail shows the 'shopping list' - I had the idea to take a photo of it on my phone, so I have it with me at all times, but somehow forgot the rum... but it is a 'school night' so I guess that is a good job
