Heat 2 tablespoons of olive oil in a large skillet over medium-high heat. Once the oil is hot, add the chicken slices. Cook for about 8 to 10 minutes, stirring occasionally, until the chicken turns golden and is cooked through.
Next, add the broccoli florets, zucchini, bell pepper, yellow onion, and garlic to the skillet. Stir well to combine all the ingredients.
Season the mixture with Italian seasoning, salt, and black pepper. Stir everything together and cook for an additional 4 to 5 minutes until the vegetables are tender but still vibrant.
Once everything is cooked, taste and adjust seasoning if necessary. The chicken should be golden and the vegetables tender.
Serve the stir-fry with rice, pasta, or simply enjoy it on its own for a low-carb option!
