01 - In a mixing bowl, whisk together eggs, low-fat milk, salt, and black pepper until fully blended.

03 - Incorporate chopped spinach into the skillet and cook for 1 minute until wilted.
04 - Reduce heat to low and pour in the egg mixture. Gently scramble, stirring consistently, until eggs are softly set, approximately 3 minutes.

07 - Heat tortillas briefly in a dry pan or microwave for 15 seconds until pliable.
