There are sooo many ways this can be fixed. My version used about 3 pounds of chicken breasts, 2 cans fire roasted tomatoes, 1 can of chicken broth, 2 packets of taco seasoning mix, and 1 large jar of salsa con queso.
Spray crockpot with non stick cooking spray, lay chicken in bottom. Sprinkle taco seasoning over the chicken. Top with the tomatoes and chicken broth. Cook on low until chicken reaches 165 degrees. Drain chicken and tomatoes. Return to crockpot, add in the jar of salsa con queso, mix well. Let the cheese heat up, then serve as you desire. We used tortillas with lettuce and sour cream. Yummy!
