01 - Whisk together eggs, low-fat milk, salt, and black pepper in a medium mixing bowl until fully blended.

03 - Add chopped spinach to the pan and cook for 1 minute until leaves are wilted.
04 - Lower heat to a gentle setting. Pour in the egg mixture and softly scramble, stirring, until eggs are just set, about 3 minutes.
