In a high-speed blender, combine the rolled oats, half of the banana, eggs, egg whites, cinnamon, sea salt, and vanilla extract.
Blend on high until the batter is completely smooth and the oats have reached a fine flour-like consistency.
Heat a large non-stick skillet over medium-low heat and lightly grease with a small portion of the ghee.
Pour the batter into the skillet to form three or four medium-sized pancakes, cooking for 3-4 minutes until bubbles form on the surface.
Flip the pancakes carefully and cook for an additional 2 minutes until the bottoms are golden brown, then remove from the pan and set aside.
Slice the remaining half of the banana into rounds.
Add the remaining ghee to the same skillet and sauté the banana slices for 1-2 minutes per side until they are soft and deeply caramelized.
Plate the pancakes, top with the warm caramelized bananas, and serve with the Greek yogurt on the side for a protein-packed finish.
