"Peanuts are an important part of many African cuisines. Combined with sweet potatoes, chickpeas, and kale, they give this stew a power punch of nutrients and great flavor. Serve with rice or bread and a salad."
Heat oil in a large saucepan over medium heat. Add 2 tablespoons vegetable stock, onion, and garlic. Cook and stir until onion is soft, 3 to 5 minutes. Add remaining stock, sweet potatoes, chickpeas, brown rice, and salt. Bring to a boil. Reduce heat and cover the stew. Simmer until sweet potatoes and rice are tender, about 45 minutes.
Combine peanut butter with 1/2 cup of the liquid from the stew. Stir into a smooth paste.
Add the peanut butter mixture and kale to the stew. Cook until kale is wilted, about 5 minutes. Stir in lemon juice, soy sauce, and hot pepper sauce.
