1. Prepare the Chicken

1. Cut the chicken breasts into 1-inch pieces and season with salt and pepper.
2. In a small bowl, combine garlic powder, onion powder, thyme, rosemary, paprika, and chili powder.
3. Sprinkle half of the seasoning mix over the chicken pieces.
4. Drizzle ½ tablespoon of olive oil over the chicken, tossing to coat evenly.

2. Cook the Chicken

1. Heat 1 tablespoon of olive oil in a large 12-inch skillet over medium-high heat.
2. Add the chicken and cook for 6 to 8 minutes, stirring occasionally, until browned and fully cooked through.
3. Transfer the cooked chicken to a plate, cover, and set aside.

3. Sauté the Vegetables

1. Return the skillet to the heat and add the remaining olive oil.
2. Add the sliced onions and cook for 2 minutes until softened.
3. Stir in the broccoli, zucchini, and bell peppers.
4. If needed, add a little more oil and season with the remaining spice mix, plus additional salt and pepper to taste.
5. Cook for 4 to 6 minutes, stirring occasionally, until the vegetables are crisp-tender.

4. Combine and Finish

1. Pour in the ¼ cup of chicken broth, stirring to deglaze the pan and combine flavors.
2. Return the cooked chicken (along with any juices) to the skillet and stir everything together.
3. Let it cook for another minute, allowing the flavors to meld.

5. Serve and Garnish

1. Remove from heat and taste, adjusting seasoning if needed.
2. Garnish with fresh chopped parsley and serve immediately.
