Melt butter in a saucepan over medium heat then whisk in flour until smooth. Cook, whisking constantly for 1 minute. Gradually whisk in milk and cook over medium, whisking constantly until thickened, about 5 minutes. Remove from heat, and whisk in cheese, chiles, and salt.

Cook sausage. Remove from pan and drain if necessary.

Melt butter in a very large skillet over medium heat. Add green onions and cilantro, and saute. Add eggs, salt, and pepper, and cook, without stirring, until eggs begin to set, then bring a spatula across the bottom of the pan to distribute uncooked eggs. Continue to cook until eggs are thickened but still moist. Remove from heat, and gently fold in the sausage and 1 1/2 cups of the Cheese Sauce.

Spoon 1/3 cup of the egg mixture down the center of each tortilla and roll up. Place seam side down in a lightly greased 13x9 baking dish. Repeat for all 8 tortillas. Pour remaining Cheese Sauce evenly over tortillas, then sprinkle evenly with pepper jack cheese. Refrigerate until 45 minutes before meal time (overnight is OK.)

Bake at 350 for 30 minutes or until cheese is bubbly. Sprinkle with toppings, serve with hot sauce and salsa.
