Heat 1 tablespoon of olive oil in a large skillet over medium-high heat.
Season the chicken with salt, pepper, garlic powder, onion powder, thyme, rosemary, paprika, and chili powder.
Add the chicken to the skillet and cook for 5-6 minutes, stirring occasionally, until golden brown and cooked through. Remove from skillet and set aside.
Add the remaining 1 tablespoon of olive oil to the skillet. Toss in the onion and sauté for 2 minutes until softened.
Stir in the broccoli, zucchini, yellow bell pepper, and red bell pepper. Cook for 5-7 minutes, stirring occasionally, until vegetables are tender-crisp.
Pour in the chicken broth to deglaze the pan, scraping up any browned bits.
Return the cooked chicken to the skillet, stirring to combine, and let it simmer for 2-3 minutes.
Remove from heat, garnish with fresh parsley, and serve immediately.
