Brown sausage links in a large skillet over medium-high heat for 5 minutes, turning occasionally, then remove and slice into 1-inch pieces.
In the same skillet, sauté diced onion and peppers in olive oil for 4 minutes until softened, then add minced garlic and cook 1 minute more.
Add drained beans, diced tomatoes with juice, and sliced sausage back to the pan, then simmer for 8 minutes until flavors meld.
Taste and adjust salt as needed, then divide among bowls and serve hot.
