Add the avocado or coconut oil to a large skillet over medium heat with the shredded rotisserie chicken. Add the Pico de Gallo, water, and taco seasoning. Mix well to coat the chicken.
Serve with taco shells and top with desired toppings (shredded lettuce, guacamole, cilantro, shredded cheese)
Tip: You can swap out the taco shells for lettuce leaves!
