This picture makes this look like nothing, but wow! So delish, I couldn't believe it. :) I made my salsa verde from scratch, so it is super spicy (I'm having a love affair w/Serranos)
In medium bowl, mix salsa verde and sour cream.
Break up chips into bite-size pieces. Place half of chips in casserole. Top with shredded chicken, followed by half of salsa mixture. Top with half of the cheese.
Repeat with remaining chips, salsa mixture and cheese.
Bake about 30 minutes or until cheese is melted and top is golden brown. Let stand 5 minutes before serving.
