Heat 8 Quart Stock Pot over medium heat for 1 minute. Add olive oil, onions, carrots, fennel and garlic to the stock pot, and season with salt.
Cook the vegetables for about 5 minutes, stirring occasionally, until they are softened.
Stir in the broth, tomatoes, beans, kale, zucchini, squash and bell pepper. Season with black pepper.
Cover and cook over medium heat until steam begins to escape from under the lid, about 5 minutes.
Spin the lid to engage the Vapor Seal then immediately reduce the heat to low. Cook until the vegetables are tender, 20 to 30 minutes. (After about 10 minutes give the lid a quick spin—if it spins easily, leave it alone until it’s done. If not, increase the heat to re-engage the Vapor Seal, then reduce the heat to medium-low and continue cooking as directed.)
