01 - Whisk together eggs, milk, salt, and pepper in a medium bowl until fully combined and uniform in color.
02 - Fry bacon in a large non-stick skillet over medium heat until crispy and browned. Transfer to paper towels to drain, crumble once cooled, and reserve about 1 teaspoon of rendered fat in the pan.
03 - Add diced bell pepper to the skillet and sauté for 2 minutes until slightly softened. Toss in chopped spinach and cook for 1 additional minute until just wilted.
04 - Reduce heat to low. Add butter and let it melt, then pour in the egg mixture. Allow to sit undisturbed for 30 seconds, then gently push eggs across the pan with a spatula, folding curds over themselves repeatedly.
05 - When eggs are softly set but still slightly glossy, sprinkle with cheddar cheese, crumbled bacon, and green onions. Gently fold until cheese melts and eggs reach desired consistency.
06 - Plate the loaded scrambled eggs while hot, garnishing with additional green onions if desired. Serve promptly for best texture and flavor.
