In a large pan set over medium high heat, add the sausage links with the casings removed. Break up the sausage in the pan and brown until you have cooked sausage crumbles, about 6 minutes.
Add the zucchini slices, 1 Tablespoon water or white wine, and salt. Cook for 4 minutes or until zucchini just starts to soften.
Add the garlic and olive oil to the pan and cook for 1 minute, stirring frequently.
Add the white beans to the pan and cook for 2 more minutes, stirring occasionally.
Serve with toast brushed with olive oil.
