Wrap the flour tortillas in paper towels and microwave them for 1 minute to make them pliable. Set them aside.
Crumble the sausage finely into a large skillet over a medium heat and cook until brown, 5 to 6 minutes.
Add the butter to a large nonstick skillet over a medium heat. Beat the eggs in a large bowl with the salt and pepper. Stir in the hot sauce, jalapenos and a splash of jalapeno juice. When the butter has melted, turn the heat to low and pour in the eggs, then add the sausage. Slowly cook the mixture, using a wooden spatula to push it around the skillet, until the eggs are totally cooked through, 8 to 10 minutes.
Place approximately 1/2 cup of the egg and sausage mixture into a warm tortilla, then add a pinch of cheese and roll up (do not tuck in the ends). Wrap in a foil square and keep warm until ready to serve. Repeat with the remaining ingredients. Serve with more hot sauce, jalapenos and salsa.
