Cut the chicken breast into 1-inch pieces and season with salt and pepper.

Mix garlic powder, onion powder, dried thyme, dried rosemary, paprika, and chili powder in a bowl. Set aside half for the vegetables.

Heat olive oil in a skillet over medium-high heat, add chicken in a single layer, and sauté for 6-8 minutes until cooked through.

In the same skillet, add the sliced onion and cook for 2 minutes. Then add broccoli, zucchini, and bell peppers with the remaining seasoning. Sauté for 4-6 minutes.

Pour in chicken broth, return chicken to skillet, and stir. Simmer for 1 minute until heated through.

Remove from heat, garnish with parsley, and serve.
