Start with several mushrooms (medium to small; they need to be bite-sized)
Holding the mushroom, grab the stem and twist to remove it.
Set the stem aside. We won't be using them.
Cut a piece of string cheese into small pieces, one piece per mushroom.
Sprinkle garlic powder and Onion and Herb Mrs. Dash inside the mushroom caps.
Place a piece of the string cheese inside each cap, drizzle with olive oil, and sprinkle with salt.
Bake at 350 for 8 minutes. Take the mushrooms out and sprinkle with shredded mozzarella cheese. Put the mushrooms back in the oven until the shredded cheese is melty and creamy. Let the mushrooms cool a little before you eat one. The liquid that comes from the mushroom as it bakes gets extremely hot!
