1: Peel and rinse 2 spring onions (scallions), keeping only the tender tops (use any swollen bulbs in another recipe).
2: Slice the spring onions.
3: Pour 2 tablespoons olive oil into a small frying pan on medium heat. When really hot, add the onions, salt and pepper, and cook for 1 or 2 minutes without colouring. Set aside.
4: Use the same pan to lightly brown 4 slices smoked ham on both sides. Do this in batches if necessary.
5: Preheat the oven to 390°F (200°C). Arrange 4 slices bread on a baking sheet.
6: Lay a slice of fried ham on each slice.
7: Spread the onions over the slices.
8: Slice 100 g Morbier cheese thinly and divide between the slcies.
9: Bake for about 15 minutes and serve piping hot.
Remarks
If you don't have Morbier, use any other cheese you like, though preferably a soft type. However, this is not essential. The same goes for the ham: use whatever you prefer.
