1. Peel the onion and slice it thinly. Heat half the oil in a frying pan over low heat, add the onion and a pinch of salt, cover and cook gently for 12 minutes, stirring now and then, until soft and golden; deglaze with the balsamic vinegar and let it bubble for 1 minute.
2. Meanwhile wipe the mushrooms with a damp cloth, trim the base of the stalks and slice them.
3. In another pan heat the remaining oil over high heat and sauté the mushrooms for 6 minutes, until their liquid has evaporated and they are golden; season with salt and finish with chopped parsley.
4. Season the mince with salt and pepper and shape a burger about 2 cm thick; cook it on a hot griddle over medium-high heat for 4 minutes per side, until well browned and cooked through.
5. Serve the burger topped with the onions, with the mushrooms and the multigrain bread.
