In a skillet, cook the breakfast sausage over medium heat, breaking it apart, until it is browned and cooked through. Drain any excess grease and set the sausage aside.

In a medium bowl, whisk together the eggs, milk, salt, and pepper until well combined.

Pour the egg mixture into the same skillet (or a clean one if preferred) over medium heat. Scramble the eggs until they are cooked to your desired consistency. Remove from heat.

Warm the flour tortillas according to package directions, either in a microwave or a dry skillet, to make them pliable.

Lay each warm tortilla flat. Spoon a portion of the scrambled eggs onto the center of each tortilla, followed by a sprinkle of cooked sausage and shredded cheddar cheese.

To roll up, fold in the sides of the tortilla over the filling, then tightly roll it from the bottom up.

Serve the Sausage Egg Breakfast Roll-Ups immediately with your favorite optional toppings like salsa, sour cream, or hot sauce.
