01 - Whisk together eggs, milk, salt, and pepper in a medium bowl until thoroughly combined and uniform in color.
02 - Fry bacon in a large non-stick skillet over medium heat until crispy. Transfer to paper towel-lined plate, crumble after cooling, and retain 1 teaspoon of rendered fat in the pan.
03 - Add diced bell pepper to the skillet and cook for 2 minutes until softened. Toss in spinach and sauté for 1 minute until wilted.
04 - Reduce heat to low. Melt butter in the pan, pour in egg mixture, and let sit undisturbed for 30 seconds. Gently push eggs across the pan with a spatula, allowing uncooked portions to flow underneath.
05 - When eggs are softly set but slightly glossy, sprinkle cheddar cheese, crumbled bacon, and green onions over the surface. Fold gently until cheese melts and eggs reach desired consistency.
06 - Transfer to plates immediately while hot. Garnish with additional sliced green onions if preferred.
