Slice your bread into 2cm slices. Place into a hot oven for 5-8 minutes to crisp up. In the meantime, slice your leeks.
Melt the butter over a medium heat and add the leeks. Cook for a couple of minutes until they are soft.
Stir in the mustard powder and flour, it should become very thick. Then add in the milk, constantly stirring to make a thick sauce. Continue to cook the sauce for a few minutes.
Stir in your chosen cheese until melted and season to your liking.
Spoon the leek mixture onto your bread, brown under the grill and serve. Enjoy!
