My favourite unusual one is sichuan pepper powder on garlic bread. Originated in me rummaging through my spices for stuff to add to my garlic bread and I really liked this. I now add it to garlic bread, pizzas, that sort of thing.
Cumin is also a great all purpose spice I put on many things. Cumin+turmeric for curry-flavoured things, but also cumin+salt+pepper+rosemary+garlic granules for anything roasted.
