01 - Whisk together eggs, milk, salt, and pepper in a medium bowl until thoroughly combined and uniform in color.
02 - Cook bacon in a large non-stick skillet over medium heat until crispy. Transfer to a paper towel-lined plate, crumble after cooling, and wipe excess fat from the pan, leaving approximately 1 teaspoon.
03 - Add diced bell pepper to the skillet and sauté for 2 minutes until softened. Add chopped spinach and cook for 1 minute until wilted.
04 - Reduce heat to low. Add butter, then pour in the egg mixture. Let sit undisturbed for 30 seconds, then gently push eggs across the pan with a spatula, allowing curds to form.
05 - When eggs are softly set but slightly moist, sprinkle cheddar cheese, crumbled bacon, and green onions over the top. Gently fold until cheese melts and eggs reach desired consistency.
06 - Plate immediately while hot, garnishing with additional green onions if preferred.
