Preheat the oven to 375 degrees.
In a small bowl mix together rotisserie chicken, chili powder, garlic powder, and mozzarella cheese.
Roll the chicken mixture in the tortillas and place in a casserole dish. This should make a dozen enchiladas.
Mix together the sour cream, heavy cream, cream cheese, and green chilis until smooth.
When ready to put the enchiladas in the oven, pour the cream mixture over the top. Top each enchilada with a jalapeño.
Place in the oven and cook for 20-30 minutes, until bubbly.
Remove from oven and serve.
