Season the sirloin steak with garlic powder, half of the sea salt, and half of the black pepper.
Heat a small cast-iron skillet over medium-high heat and sear the steak for 3-4 minutes per side until medium-rare; let it rest for 5 minutes before slicing thinly.
Bring a small pot of water to a gentle simmer with a splash of vinegar. Crack the two whole eggs into the water and poach for 3 minutes until the whites are set but yolks remain runny.
In a small heat-proof bowl set over the simmering water, whisk the single egg yolk and lemon juice until thickened.
Slowly drizzle the melted ghee into the yolk mixture while whisking constantly to create a smooth, emulsified hollandaise sauce.
Toast the sprouted grain bread until golden and crisp.
Place the sliced steak onto the toast, top with the poached eggs, and drizzle with the warm hollandaise sauce.
Garnish with the remaining salt, pepper, and fresh chopped chives before serving immediately.
