Tinned Tomatoes are popular aren't they?
Tinned tomatoes (plum and chopped), Sweet corn, Mackerel & Sardines for me, Tuna for mum, Danish Ham (Tescos, used to be £1.10, now £1.80, I have a few in stock.....) Anchovies (watched an episode of Bones and Puttenesca was mentioned, found a recipe, took 3 attempts with tweaks until it was perfect for me! Gave some to my sister, a friend of hers was there, she tried it and said it was better than her version! Gave her a copy of my version and apparently the family of 5 scoffed everything and asked for more!)
Tinned mushrooms, tomato puree, (these 2 for chilli). I do buy jars of curry sauces as they get whacked in the slow cooker.
We're Armageddon ready here, mum brought us up for always having grub in stock in case snowed in! Might not get the snow the same but we do stock up. Also, DON'T keep it all in one place, we had a fire some years ago and it took out all our food including the freezers!
