- Cook the pasta in boiling water according to the instructions on the packet, without adding salt. When cooked, drain and cover.
- Meanwhile, you can also boil the cauliflower in a pot of water for about 15 minutes until the cauliflower is soft. When the cauliflower is cooked, drain it using a colander.
- Spoon the cauliflower into an ovenproof dish, along with most of the pasta – leaving about 10 pasta pieces aside.
- In a small bowl and using a spoon, mix the cornflour with a little milk to make a paste.
- Put the rest of the milk in a saucepan and heat it on the hob until it starts to boil.
- Add the cornflour paste and keep stirring until the milk becomes thicker.
- Stir in the mustard powder and half of the cheese.
- Pour the cheesy sauce over the cauliflower and pasta.
- Sprinkle the rest of the cheese over the top.
- Place under a grill until it is golden and bubbling.
- Once cooked, you can monster-fy your cauliflower cheese! Stick in the saved pasta pieces to look like spiky hair, add some radishes for eyes, curly leaf parsley for eyebrows and a slice of pepper for the mouth and nose. Now you have your cheesy cauliflower monster!
