Method

1. Preheat a fan oven to 220 °C, with the grill on if you have one, and line a small baking tray with baking paper.
2. Make the béchamel: melt the butter in a small pan over low heat, add the flour and whisk for 1 minute; pour in the skimmed milk a little at a time, whisking, and cook for 3 minutes, until it coats the spoon. Season with a grating of nutmeg.
3. Grate the Gruyère. Spread the mustard on one slice of sandwich bread, top with the ham and half the Gruyère and close with another slice.
4. Put the sandwich on the tray, cover it with the béchamel and sprinkle with the remaining Gruyère.
5. Bake for 10 minutes, until the top is golden and bubbling.
6. Meanwhile wash and dry the mixed salad and serve it alongside the croque monsieur.
