Start by placing the boneless, skinless chicken breasts at the bottom of the slow cooker. This allows the chicken to cook evenly and soak up all the delicious flavors.
Pour the 3 cups of salsa over the chicken, followed by the ground cumin and chili powder. These spices will create a rich and flavorful base for your tacos.
Next, add the low-sodium chicken broth, corn kernels, and black beans to the slow cooker. Gently stir to combine all the ingredients, ensuring the chicken is well-coated with the salsa mixture.
Cover the slow cooker and set it to low for 6-8 hours or high for 3-4 hours. The long, slow cooking process will yield tender chicken that shreds easily.
Once the cooking time is up, remove the chicken breasts from the slow cooker. Use two forks to shred the chicken, then return it to the slow cooker, stirring it back into the salsa mixture.
Warm the whole-wheat flour tortillas in a dry skillet or microwave. This step makes them pliable and perfect for folding.
Spoon the shredded chicken mixture onto each tortilla. Top with shredded romaine lettuce, diced tomato, shredded cheddar cheese, diced avocado, and a dollop of plain Greek yogurt.
