Preheat the oven to 350 degrees and spray a 7x11 baking dish with non-stick cooking spray. Set aside.
In a large bowl, add both shredded cheese and diced green chiles. Stir to combine.
In a medium bowl, add enchilada sauce and sour cream. Whisk to combine.
Wrap flour tortillas in damp paper towels and microwave for 20 seconds(?)
Dip a tortilla into the sauce and place in the baking dish.
Next, add shredded cheese mixture in the center of the dipped tortilla and roll up. Place on one end of the baking dish.
Repeat with the remaining tortillas.
Once the baking dish is full, pour the remaining enchilada sauce mixture over the top and sprinkle with remaining cheese.
Cover with aluminum foil and bake for 15 minutes. Remove the foil and bake for an additional 10 minutes.
