In a large pot heat the oil, add chopped onion and cook until soft (about 3 mins). Add garlic and cook until fragrant. Add the tomato sauce, stir. Add in spices, vegetable base, water and lentil, stir and cover. Cook for approximately 30 mins then add in the chickpeas.
Take 2 cups of the soup from pot and blend it for 30 secs* if using a Vitamix. Pour the blended soup back in the pot. Add collar greens (or kale) and let it simmer for 5 minutes.
Serve with roasted chickpeas, fresh scallion, toasted sesame seeds or coconut cream.
