Cook your chicken with your favorite seasonings, even if just salt and pepper. I personally like to add garlic salt to mine.
In a medium bowl, mix chicken, monterey jack cheese and one can of green chilies together.
Put equal portions of the mixture onto each tortillas using a big spoon, line them up enclosed side face down in a 9x13 dish.
Melt butter in a saucepan, then add flour and stir until it is smoothened. Pour in the broth and when it s boiling, continue to stir until the sauce is thick. Add in the cumin, garlic powder and the last can of green chilies, stir to mix.
Pour all over the tortillas and top with cheddar cheese, and now you've got yourself enchiladas!
