Split the whole wheat English muffin and toast the halves until they are golden brown and crisp.
In a small skillet over medium heat, lightly sear the Canadian bacon slices for about 1 minute per side until warmed through.
To make the hollandaise, create a double boiler by placing a small heat-safe bowl over a pot of gently simmering water, ensuring the bowl does not touch the water.
Whisk the egg yolk, lemon juice, and Greek yogurt in the bowl until combined, then slowly drizzle in the melted ghee while whisking constantly.
Continue whisking the sauce until it thickens into a velvety consistency, then stir in the sea salt and remove from the heat.
Fill a medium saucepan with water and add the white vinegar, bringing it to a very gentle simmer.
Crack each egg into a small ramekin and carefully slide them into the simmering water, poaching for 3 minutes until the whites are opaque but the yolks are still soft.
Place the Canadian bacon on the toasted muffin halves, top each with a poached egg, and finish with a generous spoonful of hollandaise, fresh chives, and black pepper.
