Broccoli Cheese Soup

I found this recipe in the "4 Ingredients Kids" book and really enjoyed it! It's simple, tasty, fast to make and an amazingly low 120 calories per serve! You could easily use cauliflower instead of or with the broccoli. So good for these chilly evenings!

Ingredients
1 onion, finely chopped
2 heads broccoli, trimmed and chopped
6 cups vegetable stock
1/2 cup grated tasty cheese

Method
Cook onion, with 2 tablespoons water, in a large saucepan over medium heat for 4-5 minutes, or until softened, stirring occasionally.

Add broccoli and stock and bring to the boil. Reduce heat and simmer, partially covered for 20 minutes or until broccoli is tender. Purée until smooth.

Season if needed and sprinkle with cheese before serving.
