Cook cauliflower: In a large soup pan, add the cauliflower florets and enough water to almost cover them. Bring to medium heat and cover, cooking until the cauliflower is fork-tender (about 10-15 minutes).
Drain & reserve water: Drain the water, keeping it for later use.
Blend ingredients: Transfer the cooked cauliflower to a high-speed blender. Add olive oil, nutritional yeast, sage, thyme, garlic, onion flakes, salt, and pepper along with 1/4 cup of the reserved cooking liquid. Puree until smooth.
Sauté vegetables: In a separate pan, add the frozen vegetables. Sauté for 1-2 minutes until warmed through.
Add chicken: Stir in the chopped chicken until evenly mixed.
Combine broth: Mix the bouillon with 1 cup of hot water and pour into the pan, stirring to combine.
Add cauliflower mixture: Incorporate the pureed cauliflower sauce into the soup. Mix well and let it cook together for about 5 minutes until flavors meld.
Adjust consistency: If the soup feels too thick, add additional water or broth until you reach your desired consistency.
Serve: Ladle the soup into bowls and enjoy!
