Fake mac and cheese

Here is my recipe of mac and cheese, but with great volume and low calories. 370g with 390kcals.

There is actually not much cheese, but parmesan makes a great work on the flavors, and the cauliflower gives the whole recipe more volume. The ingredients I've used are:
– 50g of pasta (raw)
– 150ml of skimmed milk
– 4g of butter
– 10g of corn starch
– 40g of chicken breast
– 6g of parmesan cheese
– 1/2 Onion, chopped
– Cooked cauliflower, shredded (the amount you prefer)

Basically:
1. Cook the pasta and leave to cool;
2. Mix the milk with the cornstarch;
3. On a pan, fry the chopped onion with the butter, until onion get smooth texture;
4. Throw the milk inside the pan with the onion;
5. Add the parmesan cheese and mix on high temperature, until the mixture starts to get a little creamy;
6. Add the pasta and the cauliflower, and turn off the heat, and wait to cool a little.

And it's ready! 1 serving weights approximately 370g, but can change depending on how much cauliflower you add. The first time I've made this, I got 450g each serving!

That's it, enjoy.
