Heat olive oil in a large skillet over medium heat.
Season the chicken pieces with garlic powder, onion powder, paprika, salt, and pepper.
Add the seasoned chicken to the skillet and cook for about 5-7 minutes, stirring occasionally, until the chicken is browned and cooked through.
Add the chopped bell peppers, zucchini, and cherry tomatoes to the skillet. Sprinkle with dried Italian herbs.
Cook for an additional 5-7 minutes, stirring occasionally, until the vegetables are tender but still crisp.
Remove from heat and garnish with fresh parsley before serving.
