Le Croque Monsieur

Ingredients

Shaved leg ham.
Bread, sliced 1cm thick.
Gruyere cheese, grated.
Salad.

For the sauce:
30g butter.
30g flour.
2 tsp Dijon mustard.
150ml milk.
Pinch nutmeg.

Method

To make the sauce, combine the milk and mustard, stirring well.
Melt butter over low heat in a heavy-based saucepan and stir in the flour, cooking for 1 minute to form a roux.
Remove from heat, and gradually stir in milk/mustard mixture.
Return to heat, bring to the boil, reduce heat and stir until thickened.
Add a pinch of nutmeg, and season.

On a slice of bread arrange ham, gruyere and a layer of sauce.
Top with another slice of bread to form a sandwich.
Over medium heat, fry sandwich for 1 to 2 minutes on each side with a dash of butter.
Slice in half and serve with some salad.
