    Preheat the oven to 200'C.

    Cut the muffins in half and toast until golden brown.

    Cut the rump steak in half and season with salt. Cook in a hot frying with olive oil for 2 minutes on each side.

    Season the foie gras with salt and then cook each slice in a hot, dry frying pan until just golden on both sides. Place on a baking sheet and cook in the oven for 6 minutes.
    Remvoe from the oven and sprinkle each slice with pepper.

    Peel and finely dice the red onions.
    Add a drizzle of olive oil to the same pan used to cook the steak. Once hot, add the red onion and a pinch of salt and cook until soft and golden brown. Add the fig vinegar and cook for a further 3 to 5 mintues.

    Serve the potatoes and mushrooms in indiviudal cocottes alongside the burgers.

Chef's tip

«Keep the mushroom stalks and use in a soup or in a creamy sauce to serve with your burger.»
