Ok so Enchiladas means literally coated in chilis. Hence red enchiladas come from red chilis and green enchiladas come from green chilis. So when we say enchiladas, we are refereeing to tortillas stuffed with chicken covered in a chili sauce. (Chili as in the pepper not the meaty sauce popular all over the US). One would never really pour mole over enchiladas because the combination of sauces might not be so tastey. I think you were trying to refer to enmoladas, meaning covered in mole sauce. These are tortillas stuffed with chicken and covered in the dark mole.

saying an enchilada would be covered in mole is like asking for a chicken fajita. Fajita means skirt steak and there is no such thing as a chicken skirt steak. Or like saying cheese quesadillas, quesadilla implies cheese.
