Preheat oven to 350 degrees F and grease a 9x13 baking pan with nonstick cooking spray and set aside.

In a large saucepan, add the chicken, taco seasoning, tomatoes, sour cream and half the can of condensed soup. Heat over medium heat, stirring frequently until hot.

Remove from heat and use 2 heaping spoonfuls to spoon filling into the center of each tortilla and wrap it up. Place the tortillas seam side down and tightly tucked into the prepared pan.

Whisk together remaining condensed soup and milk and pour on top of tortillas, coating each one.

Sprinkle with cheese and bake for 20 minutes or until cheese is melted. Serve topped with chopped fresh cilantro.
