Preheat oven to 375°F.
Line a baking sheet with foil.
Lightly coat both sides of each tortilla with cooking spray and place on the lined baking sheet.
Bake for 6 minutes, turning once during cooking. Remove from oven, but do not turn off the oven.
While tortillas bake, crack eggs in a bowl.
Add milk and salt, whisking to combine.
Heat oil in a nonstick skillet over low heat. Add egg mixture to pan.
Sprinkle with beans and cilantro, and gently scramble.
Divide scrambled eggs evenly over top of each tortilla, and sprinkle with cheese.
Bake the loaded tortillas at 375°F for 3 minutes or until the tortillas are crisp and cheese is melted.
