Heat the oil over medium heat in a saucepan, then add the onion, garlic and carrot. Put the lid on and sauté for 5-8 minutes, until tender.
Add the paprika, ground cumin and tomato purée. Stir for 30 seconds, then add the stock. Cook for 10-15 minutes until the sauce has thickened and the carrots are cooked.
Add the peas and cook for 3- 5 minutes, under a lid.
Add the prawns. Put the lid on and let them steam for 3-5 minutes, until they just turn pink.
Turn off the heat, season with salt and pepper, stir in the chopped parsley and gently combine. Put the lid back on and rest for 3 minutes before serving.
