Crack the eggs into a large mixing bowl. Beat well with fork until well mixed. Can add a 1/4 - 1/2 a cup of milk or whipping cream if you like, for more creaminess.
In large skillet, cook sausage over medium high heat while cutting with a spatula to break it into small pieces, until fully cooked and no longer pink in the center. Pour out into a large bowl and set aside.
Reduce heat to medium low and pour beaten eggs into same skillet. Cook, stirring often, until eggs are scrambled and no longer runny. Pour on top of sausage in bowl and stir to combine.
Heat tortillas, one at a time, in large skillet, about ten seconds on each side. Immediately fill with a line of egg/sausage mixture and sprinkle a little cheese over top. roll up tortillas (see photos in this post for how I roll mine) and wrap each one individually in foil, twisting or folding the ends to seal.
