Peel the carrots, potatoes and onions and roughly chop them into cubes.
Add to a large saucepan, add water (800ml-1l but you can always add more if needed) and bring to boil. Add the tomato paste and season to taste with salt and pepper.
One the vegetables are soft remove them from the water with a colander or spoon, but keep the water! It has now become a delicious homemade vegetable stock.
Transfer the vegetables to a bowl and blend with hand blender.
Add the pastina to the pan and cook for 5-6 minutes or until the pastina is ready.
Pour the vegetable purée back into the pan and mix. You’ll get the most gorgeous creamy and nourishing result.
Serve with grated Parmesan cheese and a drizzle of good quality extra virgin olive oil.
