1. Spray the crockpot liner with some non-stick cooking spray. Place the chicken breasts in the crock pot. Sprinkle with taco seasoning and pour the chicken stock over top. Cover and cook on high for 1 hour. Uncover and add 1 ½ cups of the salsa. Recover and cook on low for 2 hours. Stir occasionally.
2. Uncover. Take two forks and shred the chicken. Add the remaining salsa along with the Salsa Con Queso. Stir well together. Recover and cook on low for a further 30 to 45 minutes.
3. Place about a dozen tortilla chips on each person’s plate. Top with a portion of the chicken mixture. Top with grated cheese and serve immediately with your favourite toppings.
