1. In a mixing bowl, whisk together the egg whites, whole eggs, cinnamon powder, ginger powder, vanilla essence, maple syrup, and milk until the mixture is well combined.
2. Dip each slice of protein bread into the egg mixture, making sure that each slice is thoroughly soaked.
3. Heat oil in a non-stick pan over medium heat. Once the oil is hot, add the soaked bread slices to the pan and cook for about 4-5 minutes, flipping them halfway through, until they turn golden brown and become crispy.
4. Transfer the cooked toast to a serving plate.
5. Top the toast with sliced bananas and drizzle with maple syrup for added sweetness.
6. Serve the high-protein toast immediately while it's still warm and enjoy!
Note: You can customize the toppings according to your preference. Feel free to add other fruits, nuts, or spreads like peanut butter to enhance the flavour and texture.
