Cafe Rio Chicken and cilantro lime dressing

This was really delicious!! I made the shells out of thin tortillas and baked them in some cool pans I just got to give them their shape. We added lettuce, tomatoe, crispy tortilla strips, sour cream and shredded cheese.

Chicken Tacos (Cafe Rio Shredded Chicken Copycat Recipe)
Ingredients
2.5 lbs boneless skinless chicken breast halves
3/4 cup chicken broth
1/2 cup Zesty Italian Salad dressing
1 Tbsp fresh lime juice
1 Tbsp chili powder
2 tsp onion powder
1 tsp garlic powder

Directions
Place chicken breast halves in the slow cooker. In a mixing bowl whisk together remaining ingredients. Pour mixture over chicken in slow cooker, cover slow cooker with lid. Cook chicken on low heat 6 - 8 hours. Shred chicken (it's so tender I usually just shred it in the slow cooker without even removing it), then cook shredded chicken in broth in slow cooker an additional 30 minutes on low. Drain broth from chicken. Serve warm in tacos, burritos, enchiladas, quesadillas, taquitos etc.
