If using a springform, place it on the cookie sheet to prevent any possible leakage during baking. Spray with nonstick cooking spray (cheese is sticky!)
Start layering!
Add a few tablespoons of refried beans to the bottom layer tortilla. I only used refried beans on the bottom layer.
Add the sparse amount of beef to layer.
Add a tablespoon of green chiles over beef, spreading over the layer.
Sprinkle layer with shredded cheese (as much as you like!)
Add another tortilla and continue until desired height! I felt four layers were good enough for us.
Bake 30 minutes and allow to cool about 15 minutes before removing from springform/cake pan.
Cut and serve! I like to top mine with chopped lettuce and sour cream.
