For a spicier kick, add a pinch of red pepper flakes to the egg mixture or use a hot enchilada sauce. Feel free to substitute the ham with cooked sausage, bacon, or chorizo for a different flavor profile. To prevent the tortillas from drying out, you can lightly brush them with oil before filling and rolling. Leftovers can be stored in the refrigerator for up to 3 days. Reheat in the oven or microwave until warmed through.
