To make the mushrooms, melt butter in a hot pan. Fry mushrooms and garlic until browning and tender.
Add wine, cook for 5 minutes. Add cream and simmer for 10 minutes. Season with salt and pepper.
Poach eggs 1 at a time in a pot of gently boiling water. Remove from the heat, leaving the lid on, 3-4 minutes. (see video for great poaching tips!)
Wilt spinach in a bowl of boiling water. Strain.
To serve, scoop polenta onto a plate, add the mushrooms, eggs and spinach. We then seasoned with some truffle salt...but you go ahead and decide how you will season it.
