Preheat your oven to 425°F and line a large baking sheet with parchment paper.

Whisk the eggs, milk, salt, and pepper together in a large bowl until well combined.

Melt the butter in a nonstick skillet over medium-low heat, pour in the egg mixture, and cook gently, pushing the eggs from the edges toward the center every 20 to 30 seconds until softly scrambled and just set (about 4 to 5 minutes).

Remove from heat and fold in the cooked sausage, shredded cheese, and diced green chiles.

Warm the tortillas briefly in a microwave or skillet until soft and pliable.

Lay the tortillas on a clean surface and divide the filling among them, placing it in a line slightly below the center.

Roll each tortilla tightly around the filling and place them seam-side down on the prepared baking sheet.

Lightly spray the tops with nonstick cooking spray and bake for 12 to 15 minutes until golden brown and crisp.

Let cool for 2 to 3 minutes before serving.
