Chop the spinach. In a small bowl, mix it with the cream cheese, season with salt and pepper to taste, and mix well.
After cleaning the mushrooms, separate the stems from the caps.
Place the filling into the mushroom caps, then transfer to a baking dish.
Bake in the oven at 170°C for about 25 minutes until golden brown.
Garnish the finished dish with cherry tomatoes and herbs.
