Preheat your oven to 425 degrees F.
Rinse and drain your can of beans. Then, mix them with the barbecue sauce, black pepper, and cayenne (optional).
Bake the beans in the oven for 25-30 minutes.
While beans are baking, cook the pasta from the mac and cheese boxes in salted water according to the package directions. When done, drain and set aside.
While the pasta is cooking, make the sauce. Add the flavor packets, olive oil, water, and spices into a bowl and whisk together until a creamy sauce is formed. When the pasta is done cooking, mix the sauce into the pasta.
Sauté the chopped kale in a little bit of oil. Season with a pinch each of salt + pepper. Sauté on medium heat for about 5 minutes, or until kale is wilted and starting to brown.
Lastly, add in the sautéed kale and beans to your pot of mac and cheese. Stir everything in, mixing well.
Serve in bowls with a garnish of sprouts, if you'd like.
