Split the whole wheat English muffin and toast the halves until they are golden and crisp.
In a small non-stick skillet over medium heat, lightly sear the Canadian bacon for 1-2 minutes per side until heated through and slightly browned.
Fill a medium saucepan with water and add the white vinegar; bring to a very gentle simmer.
Crack each egg into a small ramekin, then carefully slide them into the simmering water; poach for 3 minutes until the whites are opaque but the yolks remain soft.
While eggs poach, whisk together the Greek yogurt, lemon juice, Dijon mustard, turmeric, sea salt, and black pepper in a small heat-proof bowl.
Place the bowl of yogurt sauce over the simmering water for 30 seconds, whisking constantly just to take the chill off (do not let it boil or it will curdle).
Place two slices of Canadian bacon on each toasted muffin half.
Use a slotted spoon to lift the poached eggs from the water, dab them on a paper towel to remove excess moisture, and place one on each muffin.
Generously spoon the zesty yogurt hollandaise over the eggs and garnish with chopped fresh chives.
