for the sandwiches, we find the big faves are egg or egg/lettuce, ham (or any meat, but we usually use ham), tomato....

i tend to find that chucking some sausagae rolls in the oven is really useful too - so easy, and will always go down a treat... ut we also have a family of big eaters - even the kidlets will have a decent feed at something like that and then not have much dinner...

and yeah - butterfly cakes are awesome!!
