Rinse and drain the black beans.
In a frying pan, heat 1/2 tbsp of olive oil on medium heat. Once sizzling, add the black beans and add the salt, pepper, paprika, and chili powder. Stir together and cook for 5 minutes.
Add the kale leaves until they start to wilt and squeeze the lime juice into the mixture. Transfer everything to a bowl.
In the same pan, heat your tortillas until they are warm and have a slight char.
To assemble, spread a thin layer of hummus onto the tortillas. Top with the black beans and kale. Sprinkle feta on top and drizzle the tahini dressing over the tacos!
