I regret buying tinned stuff. I don't have loads but probably have about 20 tins of beans, soup, veg and fruit. We will get through it but the family are all cats bum face about it. Tinned toms and Devon custard - yes, other tins just no. I won't do this again. Next time my focus will be on having external delivery supply chains of fresh fruit and veg if I can't get to the supermarket.
If there is a next time, I will cook and freeze.
