Finely chop the onion and garlic.
Dice the carrot and celery.
In a large, heavy-based pot heat the oil, then gently sauté the onion, celery and carrots for 5 minutes until soft, then add the garlic and herbs of your choice.
Stir for a minute, then add the vegetable stock and tinned tomatoes.
Add the sprouts, then bring to a boil.
Add the pasta and green beans.
Cook, uncovered, for 10-12 minutes, stirring for a the first few minutes to prevent the pasta sinking and sticking to the base of the pan.
When the veggies are tender and the pasta is cooked, stir in the parsley.
Taste the soup and season to your liking.
Serve warm.
