Open-faced NY strip "Philly cheese steaks"

1) Preheat oven to 200C/Gas 6.

Slice the baguette into 0.5cm thick rounds, drizzle with oil, and season with salt and pepper. Spread on a baking sheet, and bake until crisp and lightly golden, about 6 mins. Transfer to a rack and cool in a single layer.

Heat 2 tbsp oil in a large skillet over medium heat. Add onions and peppers and cook, stirring often, until onions are golden brown and peppers are tender.

Season steak with salt and pepper. In another large skillet, heat remaining 2 tbsp oil over medium-high heat. Add steak and cook about 6 mins per side, or until an instant-read meat thermometer registers 63C. Set aside to cool. Slice the steak paper thin (a slicer is great for this). Keep warm until ready to assemble.

For the assembly: Lay a slice of meat on each slice of baguette toast and top with 1 tsp of caramelised onions and peppers and a drizzle of the cheese sauce. Serve.

For the cheese sauce: Melt the butter in a medium saucepan over medium heat. Stir in the flour with a wooden spoon and cook stirring constantly in a figure 8, until pale yellow, about 1 min. Slowly whisk in the milk and bring to a boil. Add the Dijon, horseradish, salt, paprika, cayenne, white pepper, and nutmeg. Reduce the heat to maintain a simmer and cook, stirring constantly, until thickened, about 6 to 8 mins. Remove from the heat and whisk in the cheeses. Set aside and keep warm.
