Cook your pasta in a pot and add your chopped kale in the last 2 min of cooking time, and set aside

In a deep pan Sautee the onions, garlic until translucent, then add your chopped butternut squash. Cook until squash is soften (but not mush)

Toss the pasta and kale with your butternut squash mixture and season it with salt and pepper to your taste. Then add 2 tbs of ricotta cheese and serve :)
