Roughly chop the onion, carrots, celery and garlic cloves.
In a large stock pot add the broth, cut up veggie, bay leaf and Parmesan rind. Season with salt and pepper. Bring to a boil, place the lid on the pot and lower the heat to medium for approximately 20 minutes. Until the veggies are soft.
Once the veggies are soft and cooked through, remove the bay leaf and rind. Strain the veggies to your blender with a cup of the liquid. Blend until smooth.
Pour the blended veggies back into the broth and stir through. Test for seasoning.
Bring soup back to a boil and add the pasta, stirring every so often, so the pasta does not stick to the bottom. Cook until the pasta is done, 6-9 minutes.
Serve in bowl, optional garnish with chopped parsley, grated parmesan cheese.
