Place the center-cut bacon in a cold skillet and turn the heat to medium, cooking until the fat renders and the bacon is crispy, about 6-8 minutes.
While the bacon cooks, whisk together the whole eggs and liquid egg whites in a small bowl until well combined and slightly frothy.
Remove the crispy bacon from the skillet and set aside on a paper towel to drain, leaving about a teaspoon of bacon fat in the pan.
Add the fresh spinach to the skillet and sauté for 1-2 minutes until just wilted, then remove the spinach from the pan.
Melt the ghee in the same skillet over medium-low heat and pour in the egg mixture, seasoning with sea salt and black pepper.
Gently fold the eggs with a spatula until they form soft, creamy curds, then stir the wilted spinach back into the eggs.
Toast the Ezekiel bread until golden and firm, then top with the scrambled egg and spinach mixture and serve with the crispy bacon slices.
