Heat large saucepan and add onion, carrot and celery - 5 minutes to soften. Then add garlic and cook for another minute. Season. Add tin of beans with its liquid, then tomatoes and stock followed by stirring in the chopped rosemary. Bring to the boil. Add pasta.

Reduce heat to low simmer, partially cover and cook until pasta is al dente - about 8 minutes. Serve with grated Parmesan and focaccia.

Tip: if you’re making this soup for more than one meal and will be reheating it, only add the pasta during the (re)heating, so the pasta is always al dente! The soup base can also be frozen for a quick meal later in the week.
