Tabouleh Stuffed Mushrooms (Mushroom Appetizer Recipe)

In this recipe, mushrooms are used as little receptacles for serving tabouleh. They make very refreshing appetizers, which pair perfectly with the beautiful weather we've had in the Bay Area. 

I pickled the mushrooms days in advance so the mushrooms aren't raw but still hold their shape and don't darken. The appetizers are assembled at the last minute and they make an ideal dish for a buffet-style party. We're hosting our  annual pool party soon, so I've been experimenting with fun, summer-y appetizers for the occasion and this mushroom dish is definitely going to make the list!
