Wipe Mushrooms and slice some of the bigger leaves lengthwise leaving the smaller leaf bundles intact.
In a large saute pan heat the oil and saute the garlic until golden brown. Add the mushrooms and salt and saute for 7-10 minutes until the mushrooms are soft.
Remove from heat and toss with freshly chopped mint and some peperoncino flakes.
Let everything cool and marinate for a few hours before serving.
