Heat the oil in a heavy-based pan and add the onion and garlic, softening for 5 minutes.
Add the carrot and celery and soften further.
Add the rest of the seasonal vegetables in order of cooking time and allow to soften slightly.
Stir in the potato, then add the stock, cannellini beans, and pasta.
Bring to the boil, then simmer for about 15 minutes until the potato and pasta are cooked.
Season to taste, drizzle with some olive oil, and serve with grated parmesan and torn mint leaves.
