Get a pan, heat a couple of tablespoons of veg oil, adda teaspoon of cumin seeds, when they start to 'pop', add a chopped onion, cook for a couple of mins, stirring frequently.
Add the cold pots, chopped up if large into 2cm cubes, then stir in salt, tumeric if you've got it, chilli, add a touch of water if they start to stick, cover and cook until warmed through, finish with some ground cumin and coriander, stir and cook for a minute or so longer, serve, garnished with fresh chopped coriander. Very Yum!
