Stack 5 tortillas on a plate with a paper towel underneath, on top & in-between each one.
Microwave for 60 seconds. This makes the tortillas soft & flexible.
Working quickly add a scoop of chicken, then beans, then cheese & roll. Place in prepared pan.
Repeat for all 20 tortillas.
Pour enchilada sauce over the top of both pans of enchiladas.
Top with remaining meat, cheese & olives.
Bake for 30-35 minutes. Remove.
Let sit 5 minutes before serving.
