Meanwhile, heat the olive oil in a medium saucepan. Add the onion and cook until soft, about 5 minutes. Stir in the tomato paste, cajun seasoning, and paprika; cook 1-2 minutes. Add the vegetable stock and bring to a simmer. Stir in the cream cheese. Once the cheese is melted, add the beans, red bell pepper, and jalapeno. Reduce heat to low and let reduce by 1/4, about 20 minutes. Stir in the kale.
