Prepare Your Ingredients: First, get everything ready. Chop the bacon, grate the cheese, chop the chives, and wash the spinach. Halve, stone, and slice the avocado, then toss it gently with a squeeze of lemon juice to prevent it from browning. Set two serving bowls aside.

Cook the Bacon: Place a large non-stick frying pan over a medium heat. Add the chopped bacon and cook for 6-8 minutes, stirring occasionally, until it's golden and crisp. Use a slotted spoon to transfer the bacon to a plate lined with kitchen paper, leaving about a teaspoon of the rendered fat in the pan.

Wilt the Spinach: Add the spinach to the same pan with the bacon fat. Cook for 1-2 minutes, stirring, just until it has wilted. Season with a tiny pinch of salt and pepper, then divide it between your two serving bowls.

Whisk the Eggs: In a separate mixing bowl, crack the eggs and add the double cream, most of the grated cheese (save a little for garnish), and a good pinch of salt and pepper. Whisk with a fork until the yolks and whites are just combined – don't over-beat them.

Scramble the Eggs: Place a small saucepan or non-stick frying pan over a low heat and add the butter. Once it's melted, pour in the egg mixture. This is where patience is key. For a guide on achieving the perfect texture, you can learn about the science behind scrambled egg techniques. Cook slowly, stirring gently and continuously with a spatula or wooden spoon, for about 4-5 minutes.

The Final Touches for the Eggs: What works best for me is to take the pan off the heat just before the eggs look fully cooked. They should still be slightly wet and soft. The residual heat will finish the cooking process. Stir in the chopped chives. This method ensures they stay creamy and don't turn rubbery.

Assemble Your Bowls: Spoon the creamy scrambled eggs into the bowls alongside the wilted spinach. Arrange the sliced avocado on top and sprinkle over the crispy bacon pieces and the remaining grated Cheddar. Finish with a final grind of black pepper. Serve immediately while everything is warm.
