Chicken Breast Stir-fry with Vegetables

Cut the chicken breast into bite-sized pieces.

Chop the onion, bell pepper, and zucchini into manageable pieces.

Heat olive oil in a pan and sauté the chicken breast.

When the chicken is halfway cooked, add the vegetables and stir-fry together.

Season with salt and pepper. Once the vegetables are softened, it's ready to serve.
