Soak and activate Chickpeas (see Activating Legumes blog) or use precooked Chickpeas
Add activated or sprouted chickpeas to a pot, bring to the boil, then simmer 45 minutes.
In a Dutch oven or large pot, heat the oil. Cook the onion over medium-high heat about 5 minutes or until soft. Push the onions to the sides of the pot and add the lamb mince. Cook the meat, breaking apart with the spatula, until nicely brown, about 5 minutes. Add the garlic, harissa (add more if you like spicy chili), paprika, and salt. Cook another 1 minute until the spices are fragrant.
Pour in the tomatoes and simmer for 15 minutes to reduce the liquid.
Add the sweet potato and the stock, bring to the boil, then reduce and cook another 15 minutes.
Remove and strain the Chickpeas form the other cooking pot. Add to the Harrissa with the Kale. Bring to the boil, reduce to low and cook another 15 minutes or until the sweet potato and chickpeas are tender and the harrias thickens.
Remove from the heat, stir in the lemon juice and lemon zest. Season with additional salt if needed.
Serve with natural Greek yoghurt and parsley
