1: Rinse, peel and finely slice 1 spring onion (scallion), keeping the white and green parts separate.
2: Heat 1 tablespoon olive oil in a small frying pan on high heat. When good and hot, add 100 g small pieces of smoked bacon. Fry until cooked, then transfer onto a plate, leaving the fat in the pan.
3: Add the white part of the spring onion to the pan, salt and pepper. Cook for 1 minute without colouring.
4: Break 2 eggs into a bowl and whisk for a few seconds.
5: Add the bacon pieces, the cooked (white) onion, the raw (green) onion and 100 g grated cheese. Salt lightly, pepper and mix well. Preheat the oven to 390°F (200°C).
8: ...and bake for about 30 minutes. Serve hot, whole or cut into chunky portions, rather like a hot open sandwich.
Remarks
If you don't have spring onions, use a baby leek instead. This basic idea for a stuffed baguette can be varied in lots of ways, changing and replacing this or that – the only limit is your imagination.
