Melt your butter over medium-high heat in a large skillet.

Whisk the eggs, water, salt, and pepper in a bowl.

Add your egg mixture to the buttered, heated skillet.

As the eggs cook, move the pan and redistribute them to cook evenly.

When the eggs are set, add your ham and cheese to one-half of the pan.

Fold the other side over the ham and cheese.

Serve!
