Croque-Madame Sandwich (Serves 6)
A Croque-Monsieur is a hot sandwich, made of two slices of buttered bread with the crusts removed, filled with thin slices of Gruyère cheese and ham. The bread is then lightly toasted in butter. A Croque-Madame is the same, but topped with an egg.

45 ml (3 tbsp) unsalted butter
45 ml (3 tbsp) flour
500 ml (2 cups) full cream milk, lukewarm 
150 g (2 ½ cups) mature cheddar, grated
25 g (½ cup) finely grated Parmesan cheese
Salt and freshly ground black pepper, to taste
Freshly grated nutmeg, to taste
12 slices sour-dough bread, toasted
30 ml (6 tsp) Dijon mustard
12 slices black pepper pastrami
30 ml (2 tbsp) canola oil
12 eggs
Rocket leafs, washed for garnish

Heat butter in a saucepan over medium-high heat. Add flour and cook, whisking, until smooth, about 1 minute. Whisk in lukewarm milk, and bring to a boil; reduce heat to medium-low and let simmer until slightly reduced and thickened, approximately 5 minutes.
Add ½ cup grated mature cheddar and the Parmesan, and whisk until smooth. Season with salt, pepper and nutmeg.
Heat the oven to high. Place 6 slices bread on a parchment paper-lined baking sheet, and spread mustard over each. Top with 2 slices pastrami and the remaining mature cheddar. Grill until cheese begins to melt, 1–2 minutes. Top with remaining bread slices, then pour a generous amount of béchamel on top of each sandwich. 
Grill until cheese sauce is bubbling and evenly browned, about 3–4 minutes.
Meanwhile, heat oil in a non-stick frying pan over medium heat. Add eggs, season with salt and pepper, and fry until whites are cooked but yolks are still runny, about 3 minutes. 
Place the eggs on top of each sandwich, and serve hot.
