Heat a skillet and place the portabella mushrooms in the pan, add a few drops of water and place a lid on top and cook until they begin to become tender, this only takes a couple minutes.

Top the mushrooms with spinach and cheese.

Oil the other side of the pan, crack the eggs and begin cooking them, place a lid on top, turn eggs when the bottoms have firmed up.

Continue covering eggs until the desired doneness is achieved.

Place mushrooms on a plate, add eggs and enjoy!
