Curried shrimp and spinach

A very simple side dish I made up on the fly last week, just to add a little something special alongside the more regular chicken curry that I made.

Fry a sliced onion long and slow until it caramelizes nicely. Add spoonfuls of ground spice (cumin, coriander, chili, and some curry paste), then a couple of chopped tomatoes. Cook until the tomatoes mash down and mingle with the spices. About 10 minutes from serving, add some generous handfuls of fresh baby spinach leaves. Stir carefully to bring them into contact with the heat and let them sweat down. Stir in a handful of shelled cooked shrimp and make sure everything is mixed in and coated with spices.
