Heat oil in a large skillet over medium. Add chicken and cook 4-6 minutes per side or until no longer pink. Shred chicken and set aside.
Meanwhile, place yogurt into a small bowl. Whisk in 1 tablespoon lime zest, 2 tablespoons lime juice, honey and remaining 1/4 teaspoon salt. Thinly slice cabbage and cube the mangoes.
Heat tortillas individually in a hot skillet for 2 minutes per side, allowing them to crisp.
