In a large stockpot or Dutch oven, heat 1 tablespoon of the oil. Brown the sausage over high heat until charred on all sides, about 4 minutes. Remove to a bowl.

Add the remaining oil and sauté the onion until translucent, 5 minutes. Stir in the garlic, paprika, chili flakes and salt; cook one minute more. Add the cherry tomatoes and cook until they’ve begun to blister, soften, and release their juices, about 5 minutes.

Return the sausage to the pot, along with the potato, stock or water, and bay leaf. Bring to a boil over high heat, then reduce to medium-low. Simmer the soup until the potatoes are tender, about 15 minutes.

Fold in the kale and beans and continue to simmer until soft, another 10 minutes. Taste for seasoning and add more salt as necessary.

Ladle the soup into bowls and enjoy alongside crusty bread.
