Ingredients:

• 3 Leeks (about 500g)
• 180g of sliced, cooked Ham (I had ham sliced)
• 30g Butter
• 30g Plain Flour
• 150ml Dry White Wine
• 250ml Milk
• 1 tbsp Wholegrain Mustard
• 1 tsp chopped fresh Thyme leaves, plus a little extra to serve
• 75g Grated Cheddar

• 100g Brie, sliced

Method

1. Heat the oven to 200°C /180°fan/gas 6. Cut the Leeks into 8cm lengths, then wrap each in a piece of Ham.  If the ham is already sliced then just sprinkle it in. Arrange in the base of a large ovenproof dish.
2. Meanwhile, melt the Butter in a pan, then stir in the Flour and cook over a medium heat for 2-3 minutes. Gradually whisk in the Wine and Milk. Bring to the boil, then simmer for 3 minutes.
3. Stir in the Wholegrain Mustard, Thyme leaves and Cheddar until melted, then pour over the Leeks. Top with the Brie, then bake for 30 minutes until bubbling. Scatter with more Thyme and serve with Crusty Bread.
