Pepperoni Stuffed Mushrooms

24 large button mushrooms, cleaned
2 Tbsp butter
1 small onion, minced
3/4 cup diced pepperoni
1 clove garlic, minced
1/2 cup crushed buttery round crackers
3 Tbsp grated Parmesan cheese
1/4 tsp dried oregano
1 pinch salt
1 pinch ground black pepper
3/4 cup chicken broth

Preheat oven to 325 degrees.  Lightly grease baking sheet.  Remove and chop mushroom stems.  Set caps to the side.  Melt butter in a skillet over medium heat.  Add mushroom stems, onion, pepperoni, and garlic and cook until onions are tender.  Stir in cracker crumbs, parmesan cheese, oregano, salt, pepper, and chicken broth;  remove from heat and allow to cool to the touch.  Arrange mushroom caps on prepared baking sheet, then stuff with pepperoni mixture.  Bake until filling is hot and mushrooms are cooked through, 25-30 minutes.
