Heat butter or olive oil in a non-stick skillet over medium heat until shimmering. While the skillet heats, crack eggs into a small bowl, add a pinch of salt and pepper, and whisk until well combined and slightly frothy.
Add fresh spinach to the hot skillet and sauté for 1-2 minutes, stirring occasionally, until the spinach is just wilted. Spread the spinach evenly across the bottom of the skillet.
Pour the whisked eggs over the wilted spinach. Let the eggs set for about 30 seconds before gently pushing them towards the center with a spatula. Continue to gently scramble for 2-3 minutes until the eggs are cooked through but still moist.
Stir in the cooked bacon bits and the optional shredded cheddar cheese until the cheese is just melted and combined with the eggs.
Divide the keto scramble between two plates. Top each serving with diced ripe avocado. Serve immediately for the best taste and texture.
Notes
For an even quicker meal, use pre-cooked bacon bits or microwave-ready bacon. Feel free to add other low-carb vegetables like sliced mushrooms or bell peppers, but this might slightly increase your prep time. This meal is also great for meal prep if you cook a larger batch of the egg mixture and store the avocado separately, combining just before eating.
