If using leftover chicken, simply shred and set aside. If cooking fresh chicken, begin to cook the chicken breasts over medium heat.
While the chicken is cooking, mix the spices and salt/pepper together. Use half of the spices to cook the chicken with, and set the other half aside.
Mix the other half of the spices with the greek yogurt and juice from the lime.
Cube the mango and the avocado.
Top each tortilla with lettuce, cabbage, chicken, mango, avocado, and jerk spice sauce.
Serve and enjoy!
