Ingredients
- 225 g (8 oz) leeks, sliced
- 175 g (6 oz) carrots, diced
- 450 g (1 lb) cauliflower florets (or you can use half cauli and half broccoli if you like)
- 300 ml (10 fl oz) milk
- 50 g (2 oz) any type blue cheese
- 25 g (1 oz) cornflour
- 50 g (2 oz) grated cheese (whatever you have in the fridge)
- 2 tsp chives
- 1 tsp mustard (I use Dijon but use any you have)
- salt and ground black pepper
- 25g (1oz) grated cheese
- 15 g (1/2 oz) fresh wholemeal breadcrumbs
- Cook the leeks, carrots and cauliflower in a large saucepan of lightly salted, boiling water for 5 minutes.
- Meanwhile, gently heat the milk, cornflour and cheese together, whisking all the time until smooth. When the milk and cheese mixture is almost boiling, turn heat down and cook, stirring, until you have a thick and smooth sauce. Add chives, mustard and seasoning and stir well.
- Transfer the drained vegetables to a flameproof dish and pour over the sauce. Mix together the grated cheese and breadcrumbs and sprinkle over the top. Grill under a medium heat for 2-3 minutes until the topping is bubbling and golden. Serve at once.
