For the dish you mentioned, I would also suggest garlic powder, a little black pepper, and some sesame seeds. You could also mix in a bit (start with a teaspoon and taste) of sesame oil, which gives it a kick. You could also use a bit of powdered ginger, to extend the Asian spice palate.

Spices are wonderful ways to spruce up dishes. I haven't cooked with salt (nor put it on my food) for years. And there are even some spices, like turmeric, that are genuinely good for you!
