Rinse the quinoa under cold water until the water runs clear.
In a large heavy-bottomed pot, add quinoa, vegetable stock and oil, and bring to a boil uncovered over medium/high heat.
Once boiling, reduce heat to low and cover, checking periodically for 15 minutes.
Turn off the heat and let the quinoa steam, covered, for 5 minutes or until tender.
Fluff the quinoa in the pot and transfer to a baking tray to cool quickly.
Mix all prepared vegetables in a large bowl with the cheese and herbs.
Add the cooled quinoa and mix thoroughly.
To make your vinaigrette, use a small blender, like the thinkkitchen Ultimate Pro Blender, to purée garlic with vinegar, salt, pepper and olive oil until well blended.
