Preheat the oven to 400 degrees and heat a large, oven safe skillet to medium high heat. Wash the mushrooms and trim the stems if too long.
Add the olive oil to the hot pan and add in the washed and trimmed mushrooms.
Saute them for 2-3 minutes and then remove from heat. Flip them all over facing the same way so the stem is facing up.
In a small bowl combine the topping mixture with your hands or a spatula.
Firmly press some of the topping onto each mushroom ensuring it sticks to the stem and underside. If desired, sprinkle with additional ground pork rinds and Parmesan once all have been thoroughly coated in the topping.
Bake for 15 minutes. Serve immediately as a side dish or appetizer. Enjoy!
