To a large skillet add the oil, onion, and saute over medium-high heat for about 4 minutes or until it become lightly translucent; stir frequently.
Add the sausage and cook until it's browned and done; crumble and toss very frequently as it's cooking to ensure even cooking.
Add the garlic, tomato paste, Italian seasoning, and cook for 1 minute; stir nearly continuously.
Add the sun dried tomatoes, kale, and stir for 1-2 minutes or until kale is beginning to wilt.
Add the broth, cream, beans, stir to combine, and allow the mixture to just barely bubble. Then turn the heat down to medium-low and allow the ingredients to simmer gently for about 3-5 minutes, or until kale is tender and the sauce has thickened slightly.
Taste, and check for seasoning balance, and add salt and pepper, as desired, to taste.
Optionally, add lemon juice, fresh herbs, and serve.
