he ate a tin of tuna
Watch out for salt there Katy. Canned tuna is very high in salt. I used to only let DS have a couple of teaspoons of it even though he would happily have eaten the whole can. The tuna in oil is better than that in brine but it is still very high in salt.
I keep unsalted butter in the fridge but I chop a chunk off and keep it in a small air tight plastic container, just enough for about two days. I don't know if that would be ok where you are though!
some sandwich filling ideas
canned mackerel in mayo (again watch out for salt)
very small amount of shop bought pate (or make own unsalted or a vegi sort if you don't like livers)
grilled cheese - this works well with regular bread or pitta, grill the cheese to melting throw on any extras like tomato slices or spring onion etc and close the sandwich whilst the cheese is still hot, this way it all sticks together. Leave to cool before serving though. A less messy sandwich.
hard boiled egg mashed up with mayo or creme fraiche to bind
taramasalata (again watch for salt levels)
humous (salt again or make your own salt free at home)
Sorry I wasn't in time for your shopping trip but maybe you can try these at a later date
