In a mixing bowl, combine sliced mushrooms, 2 tablespoons of oil, and salt. Stir gently until oil is well distributed, adding up to 2 more tablespoons of oil to ensure well-covered mushrooms.

Spread the mushrooms in a single layer on a non-stick skillet over medium heat. Flip/stir every 3-5 minutes for about 15-20 minutes. Try not to over stir to allow the mushrooms to be well seared. The shiitake mushrooms are done when you take one off the pan, let it cool for a few seconds and bite down into a crispy, tasty sliver of mushroom.

These mushrooms are best enjoyed the same day you cook them.
