In a heavy-duty pot, heat 2 tablespoons of olive oil over medium heat. Add 1 pound of mild Italian sausage and 4 slices of chopped bacon, cooking for about 8-10 minutes until browned and crispy. Remove the meat and set aside, leaving about 2 tablespoons of grease.

With the residual grease in the pot, add 1 chopped onion and cook for 3-4 minutes until softened. Stir in 3 cloves of minced garlic and cook for an additional minute until fragrant.

Introduce 4 cups of cauliflower florets and 4 cups of chicken broth. Season with salt and pepper, then bring to a gentle simmer. Cover and let cook uncovered for about 15 minutes until cauliflower is tender.

Carefully transfer the mixture to a blender and blend until smooth and creamy. Ensure there are no lumps.

Return the blended mixture to the pot over gentle heat. Stir in 1 cup of half and half and add back the cooked sausage and bacon along with 2 cups of chopped kale. Simmer for an additional 5 minutes until kale wilts.

Taste and adjust seasoning with more salt and pepper. If desired, sprinkle in crushed red pepper flakes. Serve hot.
