In a microwave safe bowl, add onions, zucchini, and carrots. Cook for 4 minutes on high until onions are soft.
In the meantime, coat a large soup pot or large pan with cooking spray. Add garlic and sauté over medium high heat for 1 minute. Pour in chicken broth, vegetables from microwave, tomatoes, chicken, beans, wine, Italian seasonings and pepper. Bring up to a boil. Cover and turn down to a simmer. Cook for 25 minutes.
While soup is simmering, cook the quinoa: In a small pot, add 1 cup water and quinoa. Bring to a boil, cover, turn down to a simmer and cook for 10-12 minutes until water is absorbed. Pour into a bowl and set aside.
After cooking the soup for 25 minutes, stir in spinach and cooked quinoa. Continue to cook, covered, for 2 minutes.
Before serving, sprinkle each with 1 teaspoon Parmesan cheese, if desired.
