Preheat oven to 350 degrees F.
Spray 9x9” baking dish with cooking spray.
In a large bowl, combine shredded chicken, salsa verde, Greek yogurt, cream cheese, cumin, and salt, and mix until well combined.
Place 3 corn tortillas on bottom of baking dish. I like to place two, slightly overlapping, and cut the third one into quarters, and place the square edge at each corner of the baking dish. This way, the corners of the lasagna have tortillas in them.
Spread ? of the chicken mixture on top of the tortilla, and top with ½ cup of shredded cheese.
Continue with tortillas, chicken mixture, and cheese, until there are 3 layers. Place remaining cheese on top of casserole.
Cook for 45-50 minutes, until bubbling and cheese is golden.
Serve topped with jalapenos, cilantro, and additional dollop of Greek yogurt.
Enjoy!
