Fill a medium saucepan with water and the apple cider vinegar, bringing it to a very gentle simmer over medium-low heat.
In a small heat-proof bowl, whisk the single egg yolk, lemon juice, and Dijon mustard until the mixture is smooth and pale.
Melt the ghee in a small pan, then very slowly drizzle it into the yolk mixture while whisking constantly to create a creamy, thick emulsion.
Season the hollandaise sauce with half the sea salt and black pepper, then set the bowl over a separate pot of warm water to keep it from breaking.
Place the Canadian bacon in a dry skillet over medium heat and sear for 1-2 minutes per side until heated through and slightly browned.
Toast the sprouted English muffin half until the edges are golden and crisp.
Carefully crack the two eggs into the simmering water and poach for approximately 3 minutes until the whites are fully set but the yolks remain liquid.
Place the toasted muffin on a plate, layer with the seared Canadian bacon, and carefully top with the poached eggs.
Drizzle the warm hollandaise sauce over the eggs and garnish with the remaining salt, pepper, and fresh chives.
