Thank you for comments yesterday, sorry I didn't reply, I've got 6 year old Eldest Granddaughter here for a couple of days - makes things a little busy!
Day 31 which I decided would be the very last of the experiment because almost everything I'd bought had been eaten!
I used the other half of the home made pizza dough which I'd frozen and made a tomato topping by cooking an onion and the last tomatoes from the 4th tin and a squirt of tomato puree. Then on top I added all the remaining grated cheddar plus a good amount of the remaining parmesan and the second half of the mozzarella from out of the freezer.
I was going to take a photo but then thought it looked just like the first one I'd eaten so didn't bother again.
So what's left over from the things bought?
P.S. A brief bit of pastry info to answer a question for readers not in the UK..........
Shortcrust pastry is flour, butter in the ratio 2:1 and water and that's about all
Puff pastry is pastry that's folded and butter added and then folded again and butter added and I've never made it because it's easier to buy ready made if needed for something lighter and fluffier than shortcrust.
Flaky is Puff but without so much butter and folding and rolling - I think.
There are other sorts too like filo - never made that either.
In other words I only make ordinary what we call short-crust!
