Try making an open sandwich, using Ryvita. There are lots of different varieties available these days....my favourite is the Dark Rye.
I would put some pastrami on them, with some piccalilli or perhaps some mustard, with sliced tomatoes and cucumber. Or some smoked salmon, with Philadelphia cheese ! Yum Yum !
There are endless variations on the Ryvita open sandwich principle.
If you have an IKEA near you, try their huge round Knackebrot, with the whole in the middle...great fun to eat !
Actually, when in IKEA but some of their cod roe caviar, in the toothpaste-like tubes. Even more Yum Yum !
