Place the chicken breasts in the slow cooker and season with salt, pepper, chili powder, cumin, paprika, oregano, onion powder, and garlic powder.
Add diced tomatoes, green chilies, onion, garlic, and lime juice into the slow cooker.
Cook on low for 6-8 hours or on high for 4 hours until the chicken is tender and easily shreds with a fork.
Remove the cooked chicken, shred it, then return it to the slow cooker and mix with the sauce.
Warm tortillas. Fill each tortilla with chicken mixture.
Garnish tacos with cilantro and desired toppings like cheese, sour cream, avocado, salsa, or shredded cabbage. Enjoy
