Pre-heat the oven to 350. Lightly mist a 9x13 baking dish with cooking spray and set aside.
Stab the sweet potato 5-6 times with a fork in different places, piercing the skin. Place the potato on a plate and microwave on high for 6-8 minutes, flipping the potato over halfway through. Potato should be easy to slice when finished. Peel off the skin and dice the potato into small, bite-size pieces and set aside. You need about 6 ounces of cooked sweet potato (if you have leftover, just save it to eat separately).
In a large skillet over medium heat, cook the bacon pieces until crisp and then drain the grease. Remove the bacon to a side late and add the sausage to the pan. Cook the sausage, breaking it up with a spatula into small pieces until cooked through. Drain any remaining grease from the pan and transfer the sausage, bacon, sweet potatoes and biscuit pieces to the prepared baking dish. Stir together until well combined.
In a mixing bowl, combine the eggs, egg whites, water, salt, pepper and red pepper flakes and whisk together until beaten and well combined. Pour the egg mixture over top of the other ingredients in the baking dish and stir together so that ingredients are evenly distributed.
Bake for 25 minutes. Remove from oven and sprinkle the Cheddar over the top. Return to the oven for another 10 minutes until hot and bubbly.
