Clean mushrooms and let dry. Remove stems from mushrooms and place in resealable bag set in a bowl. In another bowl, mix oil, vinegar, pepper and the garlic and pour over the mushrooms. Place the mushrooms in the refrigerator for at least 6-24 hours (the longer the better).
Stir cream cheese and salsa together and fold in the crabmeat. Drain the marinade from the mushroom caps. Pat the caps dry. Place the mushroom caps on a baking sheet and fill with crabmeat mixture. Broil (4 inches from heat) for about 5-7 mins until hot and starts to bubble. Serve warm with extra salsa on the side and sprinkle with chopped green onions. If you want, add hot sauce to crabmeat mixture before broiling.
