In a medium bowl, beat the eggs with 1/4 teaspoon each salt and pepper.
Heat the butter in a large nonstick skillet over medium-high heat.
Cook the eggs, stirring, until set but still soft, 2 to 3 minutes.
Divide the eggs among the tortillas.
Top with whatever toppings you like. Example: avocado, salsa, Monterey Jack, and cilantro.
