After 5 minutes add 470ml (2 cups) of water into the pot (the amount of water you will need depends on how much meat you put in, just make sure the water in covering the meat as this is what will cook the inside of your meat) If you are using a pressure cooker you can let the meat cook in the water for about 15 minutes, but in any case allow it to cook until it is nice and soft on the inside Once your meat in finally cooked add the tomato purée, the harissa, the turmeric and the chilli powder, mix it around to make sure it dissolves in the water Let it sit for 2 minutes before adding the peas, the 1/2 of another onion and freshly washed parsley. Add salt if needed and serve nice warm
