Hash Brown, Blue Cheese, and Spinach Stuffed Mushrooms

I accidentally came up with this recipe when one of my vegetarian friends showed up to my all meat BBQ. Ever since then it has been a hit at every party and the most requested appetizer! If you double the recipe it can make about 100 stuffed mushrooms. Best served warm!
