On a large, oiled skillet, cook the chopped jalapeños, chipotle peppers and diced onion over medium-high heat. Sauté for 5 minutes or until the onion becomes translucent.
Add the heavy cream and cream cheese. Stir everything until cream cheese is melted.
Add the enchilada sauce and shredded chicken and mix well.
In a 13 x 9-inch baking dish lightly coated with nonstick cooking spray, place the 2 tortillas side-by-side (slightly overlapping).
Spread the chicken mixture over the tortillas and then top everything with the shredded cheese. Add the fresh jalapeños slices on top.
Cover the baking dish with foil and bake for 15 minutes.
Remove the foil and bake for an additional 15 minutes or until the cheese has lightly browned.
