Grill two pieces of beef 100 grams each until the desired roasting.
Parsnip cut into 3 slices and grilled.
Fry the mushrooms in a pan in butter until golden brown, pour in the cream and demi-glace. Boil down to the state of the sauce and bring to taste.
Arrange the parsnip slices on a plate, drizzle with the pesto and place the meat next to them.
