How to make
Clean the mushrooms and cut them into large pieces. Mix with broccoli and ham in a suitable baking container. Season with salt and pepper and place pieces of butter on them.
Put them to bake (If you put them in a ceramic pot, let the oven be cold, if you are using a baking dish - put in a warm oven).
Once they are done, sprinkle them with grated cheese. Put them back in the oven and bake until the melting of the cheese.
