Preheat the oven to 200°C
Heat the oil in a pan and sweat the shallots and celery until soft.
Add the garlic, ginger, saffron, ground cinnamon, coriander seeds, cumin seeds, paprika, 1/2 teaspoon of salt and fry with the onion for 2 minutes until the spices are fragrant.
Add the tomatoes and puree’, squash, maple syrup and water, season with salt and pepper and cook everything on a medium heat for around 30 minutes. Add more water if it starts to look too dry.
Meanwhile, pour the drained chickpeas onto a baking tray, season with salt & pepper and give a light sprinkling of smoked paprika. Place in the oven and bake for 30 minutes until golden and crispy.
For the herb & nut topping, add the fresh parsley, pistachios, olive oil and lemon juice with a good grind of pepper to a blender and whizz it up until a paste is formed.
Once the stew has been simmering for 30 minutes and the squash is tender, remove from the heat and check the chickpeas are crispy.
Ladle the stew into a bowl then dollop a couple of teaspoons of soya yoghurt and dot the topping over the top, sprinkle over the crispy chickpeas and garnish with fresh parsley and chilli.
Serve and enjoy!
