Place chicken in the crockpot with ½ the jar of one salsa.
Cook on low all day (8 hours) or high for at least four hours. You can also use the poultry setting on your Instant pot, or pick up a rotisserie chicken.
Once you are ready to assemble the enchiladas, preheat oven to 350 degrees.
Spray a 9 by 13 pan with olive or avocado oil and then spread a little bit of salsa in the bottom as well.
Using a hand mixer, shred the chicken.
Take the tortillas (if you're using corn, wrap them in damp paper towel and warm them up for 20-30 seconds in the microwave) and add the shredded chicken, some cheese and then roll them up and place it in the pan.
Repeat until you have used up your ingredients.
Once all of the enchiladas are lined up, pour the half and full jar of salsa over the top. Sprinkle any remaining cheese on the top as well.
Cover and bake at 350 degrees for 25-30 minutes, or until bubbling.
Serve with fresh cilantro, avocado, sour cream and a side salad or rice!
