Get approximately 3-4 uniformed mushrooms per expected person

Preheat oven to 350 degrees F (175C)

Remove stems from mushrooms and finely mince.

Add minced mushroom stems to saucepan with tablespoon of butter or olive oil and sautee until moisture released.

Add breadcrumbs proportionally to soak up the juices and become toasted.

Fill mushroom caps ¾ full with cheese.

Top off filled mushroom caps with breadcrumb/stem mixture and pack in.

Bake in the oven until the mushrooms are soft and tender to the touch, about 20 minutes, and you're done
