Melt butter in soup pot on medium, then add avocado oil.
Add onion, diced stems and cook 2-3 minutes stirring until soft. Stir in garlic, chili flakes, squash, thyme, sage, and cook another 2-3 minutes. Add beans, greens, broth, smoked paprika, salt and pepper.
Bring soup to a boil, then cover and reduce heat, simmering 20-25minutes until squash is tender. Soup can be eaten as is at this point, or add cream and cheese. You may choose to offer cream and cheese on the side for individual tastes and dietary needs.
Serve while hot. Store in refrigerator, covered and airtight 3-4 days. Freeze up to 3 months. Thaw in refrigerator and reheat slowly.
NOTE: If using sausage, cook raw links in boiling water. Cool to the touch, slice into ¼ inch pieces and fry in a little oil until brown on both sides. Serve by placing a few sausage slices in the bottom of individual bowls and ladle soup on top.
