Prepare the vegetables while the quinoa toasts and set the quinoa aside if it’s toasted before the vegetables are prepared.
In a large soup pot, heat oil over medium heat.
Add onion, carrot, celery, bell pepper and a large pinch of salt and sauté for 5-10 minutes until the vegetables soften slightly.
Add garlic, rosemary, thyme, bay leaf, cumin, red pepper flakes and black pepper and cook 30 seconds to 1 minute.

Bring the soup to a boil and reduce heat to a simmer
Cover and Cook until the quinoa is tender (about 30 minutes).
After 30 minutes, uncover, add the zucchini and cook 5 minutes more.
