Cook the sausage in a large skillet over medium heat, breaking it into small crumbles until no pink remains. Leave the rendered fat in the pan.

Sprinkle flour over the sausage and drippings and stir for one minute. Whisk in the milk slowly, scraping the bottom. Simmer until thick enough to coat a spoon, about five minutes. Season with salt, pepper, and cayenne.

Whisk the eggs with salt and cook in a separate nonstick pan over low heat, folding gently, until soft curds still slightly glossy. They will finish in the oven.

Spread a thin layer of gravy on the bottom of a greased 9x13 inch baking dish. Top with a layer of tortillas, half the eggs, half the remaining gravy, and half the cheese. Repeat once, ending with cheese on top.

Cover with foil and bake at 375°F for twenty minutes. Remove the foil and bake another ten to fifteen minutes until the cheese is melted and spotted with light brown. Let it rest ten minutes before slicing.
