Stuffed portobello mushrooms with spinach and truffle mayonnaise

Here's how to make it

1. Preheat the oven to 180 degrees. Place a sheet of baking paper in a baking dish.
2. Cut the stalks off the portobello mushrooms and carefully hollow them out a bit with a teaspoon.
3. Chop the shallots very finely. Chop the garlic. Heat a dash of olive oil in a large skillet or wok. Sauté the shallots for a few minutes. Then add the garlic and sauté for a minute.
4. Then add the spinach handful by hand and stir well until all the spinach has shrunk. Season to taste with some salt and pepper.
5. Fill the portobello shells with the spinach. Place them in the baking dish and bake in the oven for 12 to 15 minutes.
6. Garnish the portobello with some Parmesan cheese and small tufts of truffle mayonnaise.

Enjoy your meal!
