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 crisp. Transfer to paper towels to drain, crumble after cooling. Wipe skillet, leaving 1 teaspoon of rendered fat.
03 - Add diced bell pepper to the skillet and sauté for 2 minutes until softened. Toss in spinach and cook 1 minute until wilted.
04 - Reduce heat to low. Melt butter in skillet, pour in egg mixture. Let sit 30 seconds, then gently push eggs across the pan with spatula, folding curds as they form.
05 - When eggs are softly set but slightly glossy, sprinkle cheddar, crumbled bacon, and green onions over the surface. Fold gently just until cheese melts. Serve immediately.
