Slice the vegetables (bell peppers, onion, and zucchini) into strips. Set aside.

Season the chicken cutlets with a little black pepper and salt. Set aside.

Heat 1 tablespoon of oil in a large skillet. Once hot, add the chicken cutlets and cook until they develop a golden crust.

Once the chicken is cooked, cut it into strips and set aside.

In the same skillet, heat another tablespoon of oil over medium heat. Add the onion and sauté briefly.

Next, add one of the bell peppers.

Stir a couple of times, then add the next bell pepper.

Stir again, then add the last bell pepper.

Finally, add the zucchini, as it tends to soften quickly.

If you prefer the vegetables well-cooked, let them cook for a few more minutes. Otherwise, just stir a couple of times, then add the chicken strips and a few drops of seasoning sauce.

Mix everything together and it's ready to serve. Enjoy with spaghetti, your favorite salsa, and a couple of quesadillas.
