In a large dutch oven, heat oil and sautè onion, garlic, carrots, and celery for about 8-10 minutes until it begins to soften.
1 tablespoon olive oil, 1 large onion, 3 garlic cloves, 4 medium carrots, 4 celery stalks
If adding sausage, add here and cook until browned, about 5 minutes.
1 pound mild Italian sausage
Add salt, pepper, Italian seasoning, and red pepper flakes and stir.
1 teaspoon salt, 1 teaspoon black pepper, 2 teaspoons Italian seasoning
Add broth, beans, tomato paste, bay leaf, lemon, and optional olive oil (you can omit, but it makes it extra fantastic). Scrape the bottom of the pot once liquid is in to release any stuck on bits. Bring to a boil then reduce heat and let simmer for 25 minutes.
6-8 cups chicken or veggie broth, 2 15- ounce cans cannellini beans, 2 tablespoons tomato paste, Bay leaf, 1/2 lemon, Optional: parmesan rind to simmer, or sprig of rosemary, sage
Discard the bay leaf then transfer about 3 cups worth of soup to a blender. Blend until smooth.
Transfer back to the pot and stir well to combine. Add in the kale or spinach and let it wilt for a few minutes. Let your soup simmer! The longer the better!
2 cups chopped kale or spinach
Taste and adjust flavors as desired. I usually add a bit more lemon juice, salt and pepper!
Garnish and serve.
Optional: 1/4 cup grated parmesan cheese, Lots of fresh parsley
