Add sausage to a large stockpot and cook over medium-heat for 5-6 minutes, stirring and flipping occasionally, until the sausage is lightly browned. Use a slotted spoon to transfer the sausage to a separate plate, and set aside.

Heat the butter and olive oil in the pan over medium high heat. Once melted, add the onions and fennel and saute about 5 minutes, until beginning to soften. Add the garlic and saute 30 seconds longer, until fragrant.

Add the potatoes, carrots, beans, paprika, italian seasoning, broth, water and cooked sausage. Bring to a boil, then reduce heat and simmer, uncovered, for 15-20 minutes, until the potatoes are tender and can be pierced easily with a fork.

If you would like a thicker soup, use a potato masher to mash up some of the potatoes and beans.

Stir in the spinach and season with hot sauce, salt and pepper, to taste. Enjoy!
