Macaroni Cauliflower Cheese

1 small head of cauliflower
200g macaroni pasta

Cheese Sauce:
600ml milk
50g butter
50g flour
100g grated cheese
1 tablespoon English mustard

Preheat oven to 190c. Cut the cauliflower into florets, and boil with the pasta for 10 mins.

In the meantime, to make the cheese sauce, heat the butter in a pan then add the flour gradually to the melted butter. Stir vigorously for a minute. Remove pan from heat and stir in the milk. Place back on the heat and increase temperature, whisking the milk mixture continuously as it thickens. Bring to the boil, by which time it should have thickened, then stir in the cheese and mustard. Season to taste. Drain the pasta and cauliflower,   then tip them both into a baking dish. Top with the cheese sauce and grate a little extra Parmesan over the top. Place in oven and cook for 30 minutes or until the cheese begins to brown.
