Prepare Tomatillo Chile Sauce: In a blender or food processor, blend the tomatillos, green chile peppers, oregano, 1/4 cup cilantro leaves, parsley, onion, and garlic. Remove from blender or food processor and place in a large saucepan.
Over medium-low heat, heat the tomatillo mixture. Add evaporated milk and chicken broth; bring just to a boil. Reduce heat to medium-low; simmer until mixture has reduced to approximately 2 cups, stirring occasionally.
Remove from heat and stir in shredded chicken breast; keep warm to the side.
Soften the corn tortillas: To soften a corn tortilla, grab it with tongs, place it in hot corn oil in a skillet, turn almost immediately and then hold up to drain (you want to soften the tortilla not cook it). You can also heat them on a Comal or in the microwave if the oil part is a problem for you.
A "Comal is a flat cast iron cooking plate that goes over the fire and is used mainly for making tortillas, but also for roasting chile peppers and other vegetables. It is much like a griddle. A large cast-iron frying pan can be used instead.
Place tortillas, so they do not overlap, on a medium-hot cast-iron griddle or in a heavy frying pan over medium-high heat. Turn frequently until soft and hot (about 30 seconds on each side).
To Microwave: Place no more than 4 tortillas in at a time, arranged in a circular pattern with the edges barely overlapping. Heat for 20 seconds, turn them over and heat for 10 more seconds.
These tortillas may either be layered (stacked) or they can be rolled with the chicken placed inside instead of being cooked into the sauce. If you roll the chicken inside the tortilla, take your sauce and pour it over the rolled enchiladas.
Top with fresh cilantro leaves, chopped onion, and shredded cheese of your choice.
You are now ready to serve your enchiladas. Enjoy!
* Remove seeds and membranes for milder flavor. Wear gloves when working with fresh chile peppers and don't rub your eyes.
