Cook the sausage
In a large non-stick skillet, cook and crumble the breakfast sausage over medium-high heat until fully browned and no longer pink.
Transfer sausage to a paper towel-lined bowl to drain. Wipe out the skillet.

Scramble the eggs
Melt 2 tablespoons of butter in the same skillet over medium-high heat.
Pour in the beaten eggs. Let them set slightly, then gently stir until scrambled and almost fully cooked (still soft). Remove from heat.

Combine sausage and eggs
Remove the paper towel from under the sausage (leave sausage in the bowl). Add scrambled eggs and gently stir to combine.

Assemble the sandwiches
Wipe skillet clean and heat over medium.
Butter one side of each bread slice.
Place one slice of bread in the skillet, butter side down.

Layer the filling
Add:

• 1 slice of Colby-Jack cheese

• About 1/2 cup sausage-egg mixture

• 1 more slice of Colby-Jack cheese
  Top with another slice of bread, butter side up.

Cook until golden
Cook 3–4 minutes, until golden brown on the bottom.
Carefully flip and cook another 3–4 minutes, until golden and cheese is melted.

Serve
Remove to a cutting board and slice in half if desired. Repeat with remaining ingredients. Serve immediately.
