Dear Emma,
This type of soup us very healthy and is high in folic acid because of the amount of broccoli used.
For broccoli soup i use this recipe:
1 c. onion, diced, 1 carrot, diced, 1 celery stalk, diced, 1 clove garlic, chopped, 6 c. broccoli, chopped (about 2 crowns), 2 c. low sodium chicken broth, 2 c. skim milk, ground black pepper to taste.
And this is how is prepared:
1. In a large soup pot, combine onion, carrot, celery, garlic, and chicken broth. Bring to a boil.
2. Add the broccoli, cover the pot, and cook for 5 to 10 minutes or until broccoli is tender.
3. Allow the soup to cool and transfer the soup to a blender. Add skim milk and blend until smooth.
4. Transfer soup back to the pot and reheat the mixture slowly until heated through.
Bon appetit
