4 cups onions, sliced 1/3 inch thick
1/4 cup olive oil
Salt
3 cups celery, chopped fine, including leaves
3 cups savoy or green cabbage
2 cups lacinato kale, sliced fine
1 cup firm tomatoes, peeled and seeds removed
8 leaves basil
Broth, vegetable or chicken
1/3 cup dried Nash’s kidney beans, soaked, cooked and drained
12 slices day old bread
1/3 cup Parmigiano-Reggiano cheese
6 eggs
Place onion, salt, and olive oil in a pan and cook until onion wilts. Add celery, cabbage, and kale, and stir. Add tomatoes, basil, and broth until all veggies are covered by 2 inches, and simmer 2-3 hours. Add beans and pepper to taste.
Toast bread and soft-cook the eggs. Don’t overcook because you want the yolk runny. Place a piece of toasted bread in bottom of soup bowl, ladle the soup on top, sprinkle with some cheese, and top with an egg.
