Spicy curry fish with greens and garlic

Sometimes all you need to make fish and greens exciting again is a new spice blend.  I got some spicy curry from a Pakistani stall in the Nuovo Mercato Esquilino.  The fish is a snapper, I think.  The greens are lambs' lettuce or purslane.  They are the only vegetable that has any significant amount of omega-3 fats, so this meal packs a very healthy punch.  I've seen this kind of greens at Trader Joe's.
