Bring to a boil, reduce heat and simmer for 5 minutes to combine all of the flavours together.
Stir in the beans and spinach. Continue to simmer gently until the spinach has wilted, (about 2 minutes).
Take off heat. Stir through the parmesan cheese. Taste test, adjust salt and pepper if needed.Serve immediately.
