In a skillet over medium heat, cook the crumbled breakfast sausage until browned and fully cooked, about 5-7 minutes. Remove from the skillet and set aside.
In a bowl, whisk together the eggs, milk, salt, and pepper. Pour the egg mixture into the same skillet and scramble until fully cooked, about 3-4 minutes.
Lay the flour tortillas flat on a clean surface. Divide the cooked sausage and scrambled eggs evenly between the two tortillas.
Sprinkle the shredded cheddar cheese over the sausage and eggs on each tortilla.
Roll each tortilla tightly, starting from one end and rolling to the other, ensuring the filling stays inside.
Wipe the skillet clean and lightly coat it with cooking spray or oil. Place the rolled tortillas seam-side down in the skillet. Cook for 2-3 minutes on each side until golden brown and crispy.
Remove from the skillet, slice in half, and serve warm.
