Chop the celery and onion. Peel the garlic and run it through a garlic press or mince it.
Heat the olive oil in the sauce pot. Add the celery and onion and saute until tender. Then add the garlic and saute 30 sec until tender and aromatic.
Add the chicken broth to the pan along with the black pepper, dried basil, and garlic powder. Bring to a boil. Then add the beans, sausage and spinach. Lower the heat and simmer until thoroughly heated through about 10-15 min.
Serve up a bowl and garnish with grated parmesan or romano cheese.
Store leftovers in the refrigerator or freeze for later use.
Notes
How much salt you will have to add will depend on how much salt is in the canned beans and sausage you use.
