To make African peanut soup, take a medium-sized pot and pour the vegetable broth in it. Allow it to boil for some time. Meanwhile, sauté onions, garlic, and ginger in a frying pan till they turn light brown. Ensure that they don't burn in the process. Once done, add the sautéd ingredients to the vegetable broth and cook on medium-low heat for 20 minutes.

In the meantime, take a medium-sized heat-safe mixing bowl and mix together the tomato paste and peanut butter in the aforementioned quantities. Transfer 1-2 cups of the hot vegetable stock to the mixing bowl. Whisk all the ingredients properly until you get a smooth consistency and then pour the mixture into the medium-sized pot (previously containing the broth) and continue to mix well.

At this point, add the kale leaves (finely chopped) and season the soup with a hot sauce of your choice - in the quantity you want. In our recipe, we add sriracha sauce, which blends very well with the tomato paste. 

Now let the soup simmer for not less than 15 more minutes on medium-low heat. While it heats, keep stirring. Once done, you can either have it as a soup or serve it as a gravy over cooked brown rice. Don't forget to garnish it with chopped peanuts as they add a delightful crunch to it.
