A classic Tuscan soup. If you don't like mushy bread in your soup, leave it out and let people add it if they want. This is great to make if you have lots of vegetables in your refrigerator and don't know what to do with them. Leaving something out or replacing it would be fine. If you are making it all in one day, make sure to start early, as it takes a few hours.

1 large unpeeled Yukon Gold potato, scrubbed, cut into 1/2 inch cubes
1 small fennel bulb, trimmed, quartered through core, sliced crosswise
1 large pinch of dried thyme
1 small bunch black kale, cut crosswise into 1 inch ribbons (about 6 cups)

1 2 inch square Parmesan cheese rind
Pinch of dried crushed red pepper
2 cups (or more) Light Vegetable Broth or good quality canned vegetable broth (such as Swanson)
6 1/2 inch thick slices country white bread, coarsely torn with crusts
Combine 8 cups water, beans, sage, and sliced garlic in large saucepan. Bring to boil; reduce heat to low, cover, and simmer until beans are tender, stirring occasionally and adding more water by 1/4 cupfuls to keep beans submerged, 2 to 2 1/2 hours, depending on age of beans. Add 1 tsp sea salt; simmer 10 mins. Uncover and cool beans in liquid. DO AHEAD Can be made 1 day ahead. Cover and chill in cooking liquid.
Heat 3 tbsp oil in large pot over medium heat. Add onion; sprinkle with sea salt. Cool until onion is translucent, stirring often, about 5 mins. Add chopped garlic; stir 2 mins. Add celery, carrot, potato, fennel, and thyme; cook until vegetables are tender and begin to turn brown in spots, stirring often, 15 to 18 minutes. Add kale, chard, cabbage, tomatoes, Parmesan rind, 5 cups water, and 1 tsp sea salt. Bring to boil; reduce heat to medium-low, cover and simmer until vegetables are very tender, about 1 1/2 hours. Add beans with cooking liquid and crushed red pepper. Add 2 cups broth. Season with salt and generous amount of pepper. DO AHEAD Can be made 1 day ahead. Cool, cover and chill. Rewarm before continuing.
Add bread to soup and simmer, stirring often to break up bread into smaller pieces and adding more broth by 1/2 cupfuls to thin, if desired. Season with sea salt and pepper.
