New Caledonian burger

Instructions

1. Shape four patties about 1 cm thick, then season them with salt and pepper.
2. Heat the oil in a pan and cook the patties for 3 to 4 minutes on each side.
3. In another pan, fry the pineapple slices for 2 minutes on each side to caramelise them.
4. Cook the fried eggs in a non-stick pan until the white is set and the yolk still runny.
5. Mix the mayonnaise and ketchup to make the sauce.
6. Lightly toast the buns, spread them with sauce, then layer lettuce, tomato, patty, pineapple and egg, close up and serve straight away.
