Pre-heat oven to broil and move rack to 2nd to top position.

Clean portobellos by wiping off the dirt with a damp paper towel. Remove stems, mist with a olive oil mister, and sprinkle salt and pepper on each side. Place them on a baking sheet and broil for 3-5 minutes on each side.

Turn oven down to 400 degrees.

Remove portobellos then place the mushrooms cap side down and add shredded cheese and crack open an egg into the well of the portobello. Salt and pepper again and then bake for 15 minutes until egg white are cooked.

Remove from oven, sprinkle with parsley, and serve.
