Whizz together the ingredients for the paste in a blender or food processor - add a splash of water if you need. Mine was still too little volume for the processor so I used the pestle and mortar. Might be just as quick.,
Cook the onion in a splash olive oil for about 5 mins until softened. Stir in the mince and cook for another 5 mins to brown. Add the paste, cook for 1 min, then pour in 100ml water. Bring to the boil and simmer for 10 mins. Add the peas then simmer for a further 5 mins. Stir in the cream at the very end and heat through. Taste and add salt and pepper to taste where needed.
Meanwhile, mix together the raita ingredients and season to taste. When the mince is cooked, season and stir through the fresh coriander. Serve with the raita and brown rice, if you like.
