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. Transfer to paper towel-lined plate, crumble after cooling, and reserve 1 teaspoon of rendered fat in the pan.
03 - Add diced bell pepper to the reserved bacon fat and cook for 2 minutes until softened. Stir in chopped spinach and cook 1 minute until wilted.
04 - Reduce heat to low. Melt butter in the skillet, pour in egg mixture, and let sit undisturbed for 30 seconds. Gently push eggs across the pan with a spatula, folding curds until softly set but still slightly moist.
05 - Sprinkle cheddar cheese, crumbled bacon, and green onions over the eggs. Fold gently until cheese melts completely and eggs reach desired consistency.
06 - Plate immediately while hot, garnishing with additional green onions if preferred.
