Step 2

Place chopped fennel bulbs and next 6 ingredients in a lightly greased (with cooking spray) 5-qt. slow cooker. Top with sausage in a single layer. Cover and cook on LOW 5 hours or until vegetables are tender and sausage is cooked.

Step 3

Transfer sausage to a cutting board; cool slightly. Cut sausage diagonally into 3/4-inch-thick pieces.

Step 4

Stir sausage, beans, and radicchio into fennel mixture in slow cooker. Cover and cook on HIGH 15 minutes or until radicchio is wilted and tender. Top with cheese, and drizzle with extra virgin olive oil.
