Serves 1 but you can double up on the ingredients and make 2
Crack the eggs into a mixing bowl and whisk until evenly mixed
Slice the button mushrooms up, place them in a small bowl, add the soy sauce, then add the cup of water.
Place the mushrooms in the microwave and cook for two minutes on high. Remove with care thereafter - the bowl will be hot!
Drain the mushrooms.
Slice up the ham into thin strips.
Heat up a non-stick skillet on the stove. Add in oil once hot.
Pour the eggs into the skillet. Use your spatula and draw the egg away from the sides of the pan. Allow the egg mixture to rush in and fill those gaps - tilt the pan to encourage if necessary.
As the egg starts to cook, place your cheese, ham, and mushrooms on the left half of the omelet.
Allow to cook until you're able to flip the right half of the omelet onto the left.
Wait for the cheese to melt, then remove from the heat and serve with salt and pepper to taste.
