Initiate your culinary journey by rinsing the quinoa thoroughly. Trust me, this step is vital!
In a large pot, pour in the olive oil, warming it over medium heat.
Add the finely chopped onion and minced garlic. Stir it around for 4-5 minutes until the onions appear translucent.
Bring in the carrots and celery to the party. Sauté them for another 5 minutes.
Time for quinoa’s entrance! Pour it into the pot.
Add vegetable broth, pepper, and salt.
Let the mixture come to a boil, then reduce the heat, allowing it to simmer for about 20 minutes.
Test the quinoa. It should be fluffy and the soup’s consistency a bit thickened.
Add the fresh spinach leaves, stirring until they wilt into the soup. This should take around 3 minutes.
Finally, give it a zesty finish with lemon juice and zest. Stir it well!
