Place the chicken thighs in the slow cooker and season with salt, pepper, cumin, and chili powder.
Add the black beans, corn, diced bell peppers, diced onions, and half of the enchilada sauce over the chicken. Stir gently to combine.
Cover and cook on low heat for 6-7 hours or on high heat for 3-4 hours, until the chicken is tender and easily shredded with a fork.
Once cooked, remove the chicken thighs from the slow cooker and shred them using two forks. Return the shredded chicken to the pot and stir to combine with the vegetables and sauce.
Prepare the tortillas by warming them slightly in the microwave to make them pliable.
Spoon a generous amount of the chicken mixture into the center of each tortilla, sprinkle a small amount of cheese on top, and roll them up tightly.
Place the rolled enchiladas seam-side down in the slow cooker and pour the remaining enchilada sauce over the top. Sprinkle the rest of the cheese on top.
Cover and cook on low for an additional 30 minutes to heat through and melt the cheese.
Once ready, garnish with fresh cilantro and serve with sour cream if desired.
Notes
Serve the enchiladas on a large platter, drizzled with additional enchilada sauce and topped with chopped cilantro for a fresh touch. Accompany with lime wedges for an extra zing!
