To prepare the chicken breast, preheat the oven to 180 degrees and let it heat up. Marinate the chicken breast by rubbing it with olive oil, salt, black pepper, and garlic powder, then place it in a baking dish. Bake for approximately
20 minutes until the inside is fully cooked and it is lightly browned. After letting the chicken breast out of the oven rest at room temperature, dice it into small cubes or shred it with a fork.
