Chef John's Minestrone Soup

Heat 2 tablespoons olive oil in large stock pot over medium-high heat. Add pancetta; cook and stir until it begins to brown, 2 to 3 minutes. Stir in onions and celery; cook and stir until onions start to turn translucent, about 3 minutes. Stir in minced garlic and cook for another minute.

Pour chicken broth, water, and plum tomatoes into the pancetta and onion mixture. Bring to a simmer.

Stir cranberry beans, cabbage, garbanzo beans, red pepper flakes, Italian seasoning, and 2 teaspoons salt into broth mixture. Bring to a simmer and cook until cranberry beans are tender, adding more water as needed if the soup becomes too thick, about 45 minutes.
