Chop the shallot and cut all the mushrooms into pieces.
Put the chopped shallot in a frying pan with butter and start to sauté. Next, add the chopped mushroom mixture. Cook for 6/7 minutes.
After cooking, pour the coffee into the pan.
In another pan, sauté the spinach with the butter, adding salt and pepper to taste.
Prepare the boiled eggs: cook for 4 minutes in boiling water and then peel gently under cold running water. Make sure not to break the egg white. Add a pinch of coarse salt and a drop of vinegar (either white or red) to the water: this will make it easier to peel the eggs.
