Gingejbee:
That's the price you pay for living somewhere posh!
If I was looking for something quick and simple in Waitrose, I'd probably have half a can of haggis (£1.45 per can) with some instant mash (made with butter). Waitrose sell Smash at £1.25 for a 6-portion pouch. So, being generous with the butter, that's just a tadge over a quid for a decent meal.
. . . or perhaps I'd replace the bacon grill in my suggestion above with half a can of grilled Spam (£1.75 per can). The baked beans aren't much dearer, at 14p per portion (based upon half a can of their 'Essential' product, bought at £1.10 for 4 cans). So that's around a quid for a meal.
My canned sausages-&-beans on toast suggestion is more expensive when you have to pay 90p for the Branston product but still not massively expensive, at around a quid including the bread.
Sardines on toast would be cheap (with 'Essential' sardines in tomato sauce priced at just 49p in Waitrose).
If you've got time to cook something in the oven, my famous pilchard bake would be a possibility. Waitrose sell the pilchards in tomato sauce for 50p. The canned spuds are 47p for a 'normal' size can or 61p for a 'double' size one. You'd just need to add the cheese, mustard and black pepper (and possibly something to serve it with, such as sliced green beans or sweetcorn). Recipe here:
