Heat olive oil in a large pot over medium-high heat. Add ground mild Italian sausage and cook until browned, breaking it into large pieces as it cooks.
Remove the sausage from the pan with a slotted spoon.
Add yellow onion, celery ribs, and diced carrots to the pot. Sauté for 4-5 minutes until the vegetables are tender.
Add minced garlic and cook for 1 minute until fragrant.
Add the sausage back to the pan. Stir in salt, black pepper, drained and rinsed cannellini beans, chicken broth, and chopped kale with the stems removed.
Bring the mixture to a boil. Cover and reduce the heat to the low. Cook for 10-15 minutes until the kale is wilted and cooked through.
Serve warm topped with grated Parmesan cheese and enjoy!
