In a medium bowl, whisk together the eggs, whole milk, salt, and black pepper until fully combined.
Heat the unsalted butter in a large non-stick skillet over medium heat until melted.
Pour the egg mixture into the skillet and cook, stirring gently with a spatula, until the eggs are softly scrambled and cooked through, about 5 minutes. Remove from heat.
Add the chopped turkey sausage to the scrambled eggs and stir to combine.
Lay one flour tortilla flat on a clean surface. Evenly distribute about 1/8 of the scrambled egg and sausage mixture onto the center of the tortilla.
Sprinkle 2 tablespoons of shredded cheddar cheese over the egg mixture.
Roll the tortilla tightly around the filling, folding in the sides as you roll to form a secure roll.
Repeat the process with the remaining tortillas and filling to make 8 rolls.
Lightly spray each roll with cooking spray and wrap individually in plastic wrap or aluminum foil.
Place the wrapped rolls in a single layer in a freezer-safe container or zip-top freezer bag and freeze for up to 3 months.
To reheat, remove the plastic wrap or foil and microwave the roll on a microwave-safe plate for 1 to 2 minutes, or until heated through. Alternatively, reheat in a preheated oven at 350°F (175°C) for 15 to 20 minutes if thawed.
