Add the chicken to your slow cooker, then pour in the enchilada sauce, taco seasoning, scallions, garlic, diced tomatoes, and green chiles. Give it all a quick stir to coat the chicken.
Cover and cook on low for 6 hours or high for 4 hours until the chicken is tender.
About 30 minutes before serving, take the chicken out and shred it.
Stir the cream cheese and 1 cup of the cheddar into the slow cooker until smooth and melty, then return the shredded chicken and let it all cook together for another 15 minutes.
Stir in your cooked pasta, top with the rest of the cheese, and let it get nice and gooey.
Finish with your favorite toppings—think extra scallions, cilantro, sour cream, or a squeeze of lime—and serve!
Notes
Feel free to customize the toppings based on your preference.
