Method for stuffing and preparing the shroom burgers
1. When the mushrooms are done roasting, let sit for 10 minutes to cool slightly before stuffing with cheese.
2. Divide the cheese into 4 even portions, then roll each into a compact ball and flatten into a patty slightly smaller than the diameter of the inside of the mushrooms.
3. Each shroom burger gets two portobello mushrooms with a cheese patty in between.
4. Stuff then press down to secure the filling.
5. Dip each stuffed mushroom cap into flour, patting off the excess; then egg, letting the excess drip; then panko breadcrumbs, really pressing it in there to ensure proper stickage.
6. Make sure at each step that the mushroom caps have no bald spots.
