Preheat oven to 350. Remove stems from mushrooms and finely chop.
Heat oil in a small frying pan and add diced salami and sauté until they appear crispy. Add mushroom stems and cook another few minutes. Then add green onions, garlic and parsley, cook for 2 minutes, add wine and cook until liquid evaporates. Remove from heat and mix with mayo and breadcrumbs.
Stuff the mushrooms and place on a baking sheet or casserole, place in preheated oven and cook for about 20 minutes.
