Preheat oven to 180°.
Place a frying pan over medium heat with butter and a drizzle of olive oil.
Once butter melts, add sliced mushrooms.
Cook mushrooms for 5 mins, stirring and tossing constantly.
Add a splash of white wine and season with salt and pepper.
Let mushrooms simmer over a low heat for 5/7 mins or until the wine has been absorbed.
In the meantime, grill sliced bread on a griddle pan.
Place grilled bread on a baking tray, add Truffle Caciotta and cook in the oven until cheese is melted.
Remove bread from oven and top with mushrooms and fresh parsley to serve.
