1. Heat the olive oil in a large pan over a medium heat. Add half the sage leaves and fry until crispy, then add the garlic and chilli and fry for 1 min. Add the tomato passata and 180ml water, then reduce the heat and simmer for 15 mins with a partially covered lid. Tip in the cannellini beans, including the juice from the cans, and continue to simmer uncovered for 5 mins.
2. While you toast the bread, heat the extra virgin olive oil in a small frying pan, then add the remaining sage leaves and cook until crispy. Divide the beans between four bowls, top with the crispy sage and drizzle over the sage-infused extra virgin olive oil, then serve with the toasted ciabatta bread. Season to taste.
