Place a medium, nonstick pan over medium heat with olive oil. Wash the chicken breast and pat dry. Once dry, slice each breast into small cubes (or keep whole and shred when cooked and cooled). Toss with garlic powder, salt, and pepper.
Add the chicken to the pan and allow to cook for approximately 6-7 minutes. Or until cooked through.
While the chicken is cooking, slice the avocado, onion, tomatoes, and cucumber. Add to a large bowl.
Remove the chicken from heat once cooked. You can add the chicken while still warm or add it when its cooled. I prefer it somewhere in the middle or cooled.
To the bowl, add the chicken, mozzarella, and basil. Add in the salt, pepper, and lemon juice. Toss to coat.
Drizzle with the balsamic glaze and enjoy!
