Croque Monsieur

Croque Monsieur is a classic french dish and can be served at any time of the day. 
One of the reasons it is such a favourite might be that it is so easy to prepare, yet tastes so good.
In this version, which is from the wonderful Nigella Lawson's 'Nigella Express', you do a little preparing in the evening, and the rest is baking in the oven the next morning and voilà: a wonderful breakfast or brunch for the family without any effort! 

• 6 slices multigrain brown bread
• Dijon mustard
• 125g or 6 slices of Gruyère
•  70g or 3 slices ham
• 6 eggs
• 1/2 tsp. salt
• 80 ml milk
• 4 tbsp. grated Gruyère, Emmental or Cheddar
• Worcestershire sauce

Spread each slice of bread with mustard. Make sandwiches by putting each slice of cheese against the mustardy bread, with a slice of ham between them. Cut each sandwich in half to make triangles. 
Put the sandwiches into an ovenproof dish (approx. 27x21x6 cm) and squish them together. 
Beat together the eggs, salt and milk and then pour this over the breads. 
Cover the dish with clingfilm and leave in the fridge overnight. 
Sleeeeep!
The next morning, all you have to do is preheat the oven to 200°C, take the dish out of the fridge and remove the clingfilm. 
Sprinkle with the grated cheese and a good dose of Worcestershire sauce and bake for 25 minutes.  
You will be the hero as everyone will think that you have been up early in order to prepare breakfast! Enjoy!!
