For the Cauliflower sauce : Chop cauliflower into florets. In a large pot, boil water and add in cauliflower. Cook until tender and then drain the water. In a blender, add cauliflower, 1/2 cup of water, garlic, garlic salt and parmesan cheese. Blend until smooth. Add more water until you get your desired thickness. I added about 1 cup of water. Give it a little taste test and add in salt and pepper if needed, then set aside. Preheat oven to 400 degrees. Boil a pot of water and cook pasta according to directions. Drain and set aside. In a pot over medium heat, add spinach and cook until partially wilted. Add in pasta, chicken, ranch seasoning, garlic powder, onion powder, salt and chicken. Mix ingredients well. Add in 2 cups of cauliflower alfredo sauce and gently mix with the pasta. Take pasta mixture and add to a greased baking dish and cover with mozzarella cheese and sprinkle the top with dried parsley. Bake pasta for 8-10 minutes, or until cheese starts to turn golden brown. Enjoy!
