Greek here, totally had this (and was delicious). We didn't toast the bread either.
That also sounds a lot like the Australian 'delicacy' Fairy Bread - http://en.wikipedia.org/wiki/Fairy_bread
For another version, mix some cinnamon in with the sugar.
Can confirm it also exists in Spain and England.
Weird. I thought this "delicacy" was exclusive to Russia (we didn't toast the bread, though).
