The furikake that feorag so kindly provided has run out, and I haven't located a source yet (though I still have a couple of places to check). So I made myself this:

1 tsp sesame seeds (rather Japanese, this)
1/2 tsp mustard seeds (more Indian)
2 tsp dried wakame, crushed (definitely Japanese)
1 dried chilli, crushed (more Indian)
1 tsp salt (kinda universal...)
1/2 tsp urid daal (definitely Indian, and more specifically southern at that)

Roast everything in a dry pan. Transfer to mortar and grind. Sprinkle on stuff.

I put it on some leftover rice, but I think it would go on veg and other stuff as well. Also, next time maybe I should put in the daal first, I think it can take a bit more roasting than the rest. Should keep for a few days, but it will probably lose flavour fairly soon. Very quick to make though, and I can work on variations... :-)
