Make the mushroom sauce.
Cut the button mushrooms and shiitake mushrooms into wedges, and cut the shimeji mushrooms into bite-sized pieces.

Heat a frying pan with olive oil over high heat, add chopped garlic and heat until fragrant, then add the mushrooms and stir fry. Once the oil has been distributed evenly, add another tablespoon of olive oil

Once the ingredients have softened, add [B] and simmer

Once the water has evaporated to a certain extent, add [C] and adjust the seasoning

Sprinkle flour over the butter, then add it to [6] and mix until melted. This will thicken the sauce. Once it has thickened, remove from heat

Cook the hamburgers.
Shape the mixture into oval patties, making sure they are slightly thick. Heat a frying pan with olive oil over high heat and sear the patties quickly to brown the surface. Once browned all over, add butter for flavor and remove from the heat.

Place the hamburger steak on a plate and pour the sauce from [7] over it. Finish by sprinkling some Italian parsley on top
