Wipe out the skillet used to cook the pancakes and add the sausage patties. Cook for 3–4 minutes on each side, until the internal temperature reaches 145°F (65°C). Transfer the sausage to the baking sheet with the pancakes and keep warm while you prepare the eggs.
In a medium bowl, whisk together the remaining 4 eggs, water, and salt.
Wipe out the skillet used to cook the sausage and grease again with nonstick spray. Turn the heat to medium and heat the pan for 2 minutes, then pour in the eggs. Cook until just set on the bottom and around the edges, about 2 minutes. Transfer the pan to the oven and cook for 3–4 minutes, until set on top.
Remove the eggs from the oven and, using a rubber spatula, gently fold into a 3-inch wide omelet. Remove from the pan and cut crosswise into 4 equal pieces.
Assemble the sandwiches: Add 4 pancakes to the pan over medium heat and top each with a slice of American cheese, a sausage patty, a piece of egg, and another pancake. Cover the pan and heat over medium heat until warmed through, 2–3 minutes.
Serve hot.
Enjoy!
