01 - Whisk together eggs, milk, salt, and pepper in a medium bowl until fully blended and uniform in color.
02 - Fry bacon in a large non-stick skillet over medium heat until crisp and browned. Transfer to paper towels to drain, crumble into pieces once cooled, and reserve 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 stir for 1 minute until just wilted.
04 - Reduce heat to low setting. Melt butter in the skillet, then pour in the egg mixture. Allow to sit undisturbed for 30 seconds until edges begin to set, then gently push eggs across the pan with a spatula in sweeping motions.
05 - When eggs are soft-curded and slightly glossy, sprinkle cheddar cheese, crumbled bacon, and green onions over the surface. Fold gently until cheese melts completely and eggs reach desired doneness.
06 - Plate immediately while hot, garnishing with additional green onions if preferred.
