In a small bowl, whisk together the non-fat Greek yogurt, lemon juice, Dijon mustard, and melted ghee until the mixture is smooth and creamy.
Heat a non-stick skillet over medium-high heat and sear the Canadian bacon slices for 2 minutes per side until the edges are crispy and golden.
Add the baby spinach to the same skillet with a teaspoon of water, sautéing for 1 minute until just wilted, then remove from heat.
Fill a medium saucepan with water and the white vinegar, bringing it to a very gentle simmer.
Crack each egg into a small ramekin, create a gentle whirlpool in the water, and carefully drop the eggs in to poach for 3 minutes.
While eggs poach, split the sprouted grain English muffin and toast until golden brown.
Place the toasted muffin halves on a plate, layering each with wilted spinach and a slice of crispy Canadian bacon.
Use a slotted spoon to lift the poached eggs from the water, patting them dry before placing one on each muffin half.
Generously drizzle the yogurt hollandaise over the eggs and finish with sea salt, black pepper, and a dusting of smoked paprika.
