In a medium mixing bowl, whisk together the whole wheat flour, Greek yogurt, almond milk, one whole egg, baking powder, and cinnamon until the batter is smooth.
Preheat a large non-stick skillet over medium heat and lightly coat with a small amount of oil spray.
Pour the pancake batter into the skillet to form two medium pancakes, cooking until small bubbles appear on the surface.
Flip the pancakes and cook for another 1-2 minutes until they are golden brown and cooked through, then set aside.
In a separate skillet, heat the avocado oil over medium-high heat and add the shredded potatoes, pressing them down firmly into a flat layer.
Cook the hash browns for 4-5 minutes until the bottom is very crispy, then flip and cook for an additional 3 minutes.
While the potatoes finish, pour the liquid egg whites into the first skillet and scramble over medium heat until they are set and fluffy.
Plate the pancakes alongside the scrambled eggs and crispy hash browns, seasoning the eggs and potatoes with sea salt and black pepper.
