Heat olive oil in a large skillet or wok over medium-high heat.
Add the minced garlic and sauté for 1-2 minutes until fragrant.
Add the shredded chicken to the pan and cook for 5-7 minutes, allowing it to crisp up slightly and get a golden color.
Add the sliced zucchini and cook for another 3-4 minutes, stirring occasionally.
Season with salt and black pepper to taste.
Continue sautéing until the zucchini softens slightly but still has a bite to it, about 4-5 minutes.
Stir to combine the chicken and zucchini, making sure the flavors meld together.
Taste and adjust the seasoning as needed.
Remove from the heat once the zucchini is cooked to your liking.
Serve immediately, topped with fresh herbs, or add a sprinkle of parmesan for extra flavor.
