Pat the chicken dry and season it all over with enough salt and pepper to coat.
In a large skillet (with a lid), warm 1 tablespoon oil over medium-high heat. Add the chicken and cook for about 3-5 minutes per side or until golden and cooked through (cover with a lid to speed things along). Transfer to a cutting board to slice up later.
To the skillet over medium heat, add the remaining 1 tablespoon oil, butternut squash, and ½ teaspoon salt. Give it a stir, then cook undisturbed for 3-5 mins or until some of the squash gets browned on the bottoms.
Stir in the sage, spices, and garlic and cook for 1 minute, stirring often. Add the water, scrape up anything stuck to the bottom of the skillet, and simmer, covered, for 10 minutes or until the squash is soft and mash-able.
Use a fork or potato masher to mash up the squash. Stir in the greens, beans, and remaining ½ teaspoon salt and cook for about 1-2 minutes or until the greens are softened, stirring often. If things are looking too dry, add in about ¼ cup or more water to create a looser/saucier consistency. Stir in the butter until it’s melted.
Turn off the heat and stir in the lemon. Taste and add more salt or lemon, if needed.
Slice up the chicken. Serve the squash/beans topped with chicken, a generous dollop of ricotta, parmesan, and parsley.
