In a large pot over medium heat, sauté your onions and garlic in olive oil and butter, until translucent.
Next toss in your kale and sauté it down.
Once your kale is soft and tender, add in 28oz of crushed tomatoes, stock and water. Bring to a boil and add in your parm rind (optional).
Once your pot is at a boil, add in 12oz of tortellini and your sliced basil.
Turn your heat down and add in one cup of heavy cream and a full rotisserie. Allow all these ingredients to become friends and slowly bubble away until the pasta is fully cooked, about 7-8 min.
Season to taste with Kosher salt, black pepper and chili flakes and serve with lots of shaved parmesan.
