Brush or rub blemishes or debris from mushrooms and trim the dry area at the bottom of the stem. Cut the mushrooms in half, or if they are quite large, cut them in quarters and set aside.

Place a 10" or 12" skillet over medium heat until nice and hot. Add olive oil and only enough mushrooms to cover the bottom of the skillet in a single layer. Toss to coat the mushrooms in olive oil and move the mushrooms back into a single layer in the bottom of the pan. Allow the mushrooms to cook undisturbed for about 3–4 minutes, until the first side has begun to brown nicely. At this point toss the mushrooms occasionally for an additional 5 minutes, until they have browned nicely on all sides.

Once the mushrooms are nicely browned, season with salt or soy sauce, a light sprinkle of garlic powder and black pepper. Continue cooking for an additional 2 minutes, tossing frequently.

Remove the mushrooms from the skillet and serve immediately. Enjoy!
