In this video, we'll show you how to make a batch of taco filling. We'll start by cooking chicken breasts until tender, then shred them and mix with onions, cumin, chili powder and tomato sauce. Feel free to put your own spin on the filling by adding garlic, jalapeno peppers, and cilantro. Get the recipe for Sarah's Easy Shredded Chicken Taco Filling. Add to corn or flour tortillas and garnish with your favorite toppings.
