Preheat the grill to medium heat, hot enough that you can carefully hold your hand 3 to 4 inches above the grill grates for 3 to 5 seconds.
Line the skillet with Reynolds Wrap® Heavy Duty Aluminum Foil, leaving enough additional length to fold the foil back over to cover, ends meeting in the middle.
Place a little bit of sauce to coat the foil.
Add a layer of tortilla chips.
In a small bowl, toss the chicken with a few tablespoons of sauce.
Add a layer of chicken to the skillet.
Toss the remaining tortillas chips in the enchilada sauce and top the chicken layer with it.
Sprinkle cheese over the chip layer.
If you are adding eggs, crack an egg into a small bowl. Drop each egg carefully over the surface.
Carefully fold the overhanging foil over the layers, without letting it touch the surface of the food. Pinch the edges together.
Place the skillet over the grill and allow to cook until the eggs are set about 15 minutes.
When the eggs have set, using heat resistant gloves, carefully remove the skillet from the oven (It will be hot!) and garnish with the crema and any desired toppings.
