Drain the macaroni and cauliflower and put into a baking dish.
Pour over the cheese sauce. Mix well so that all the macaroni and cauliflower are coated.
Sprinkle over 50 g Parmesan.
Put into the oven for 20 minutes. The top should be browning and bubbling.
Notes
The cheese sauce may look runny when mixed with the macaroni, but it will thicken up as it cools.
For something a little different, we like stirring a couple of tablespoons of good quality BBQ sauce into the cheese sauce. It adds such a nice flavour.
If you wanted to really hide the cauliflower, then you could blend it into the cheese sauce.
If you love some spice in your meals, you can add a sprinkle of red chilli flakes to the cheese sauce.
