1. Preheat the oven to 400 degrees Fahrenheit.
2. Grease a muffin pan. Place one phyllo square over each muffin cup and fit into the center.
3. Remove bay leaves from mushroom mixture. Spoon two tablespoons of the mushroom mixture inside and pinch the wrapper together at the top to form a purse. Brush the dough generously with oil. Don’t worry, it won’t open.
4. Repeat with the remaining wrappers.
5. Bake until tops are beginning to turn golden at the edges, about 10 minutes. Serve warm.
