Rinse the tripe strips under cold water and pat dry with paper towels. Cut into 2 cm strips if not already cut.
Heat olive oil in a 26 cm / 10-inch Dutch oven over medium heat. Add pancetta and cook 3 to 4 minutes until the fat renders.
Add onion, carrot, celery, and garlic. Cook 6 to 8 minutes, stirring, until soft and pale gold, this is your soffritto.
Add the tripe strips and stir 2 to 3 minutes to coat them in the fat.
Pour in the wine, scraping up any browned bits, and cook until mostly evaporated, about 2 minutes.
Stir in tomato passata, broth, bay leaves, cinnamon stick, and parmesan rind. Season lightly with salt and bring to a gentle simmer.
Cover, reduce heat to low, and simmer 90 minutes, stirring occasionally, until the tripe is fork-tender and gives easily when pressed with a spoon, no spring-back.
Stir in the cannellini beans and chopped chard. Simmer uncovered 15 to 20 minutes until the chard wilts and the sauce coats the back of a spoon.
Remove the bay leaves, cinnamon stick, and parmesan rind. Taste and adjust salt and pepper.
Ladle into bowls, top with grated grana padano and black pepper, and serve hot with crusty bread.
