Ingredients
- 40 g of unsalted butter
- 2 tsp of dijon mustard
- 100 g of strong cheddar, grated
- 4 slices of stale bread
- 1 splash of worcestershire sauce, optional
- 2 leeks, trimmed, halved, washed and finely sliced
Method
Step 1
Melt the butter in a large frying pan over a medium-low heat. Add the leeks and mustard and stir to coat. Pop the lid on and sweat the leeks until meltingly soft and tender – about 10-15 mins. Season to taste.Step 2
Heat the grill, toast the bread lightly, spread the leek mixture thickly over the bread and top with the grated cheese. Grill until bubbling and golden, and serve straight away with a splash of worcestershire sauce if you like.
