Combine the butternut squash, Almond Breeze, garlic powder, smoked paprika, and nutmeg in a pot. Bring mixture to a boil over high heat, then reduce heat to low, cover, and cook for 10-15 minutes, until the squash is tender.
Add the butternut squash mixture to a blender with the white beans and blend until completely smooth. A stick blender should also work here, if you prefer.
Transfer butternut squash/bean mixture back to the pot (no heat yet). Add the cheese a little at a time, stirring until melted and incorporated. Then, add the kale.
Return the pot to heat and cook over low heat until kale is wilted. Season sauce to taste with salt and pepper.
Cook the pasta according to package directions, drain, then mix with the sauce.
Serve mac & cheese immediately or pour into a baking dish, top with additional shredded cheese, and broil until golden brown and bubbling.
