Step 1: Season and Cook the Chicken

1. In a bowl, toss the chicken pieces with olive oil, garlic powder, paprika, oregano, salt, black pepper, and lemon juice. Let it marinate for 5-10 minutes while you prepare the vegetables.
2. Heat a large skillet over medium-high heat. Once hot, add the marinated chicken. Cook for about 5-7 minutes, stirring occasionally, until the chicken is golden brown and fully cooked.
3. Remove the chicken from the skillet and set aside.

Step 2: Cook the Vegetables

1. In the same skillet, add another tablespoon of olive oil. Toss in the sliced bell peppers, zucchini, red onion, and broccoli. Sauté for about 5 minutes, stirring occasionally, until they are slightly tender but still crisp.
2. Add the minced garlic, dried thyme, basil, and red pepper flakes. Cook for another minute, stirring frequently to prevent burning.

Step 3: Combine and Finish

1. Return the cooked chicken to the skillet and toss everything together. Let it cook for another 2 minutes to allow the flavors to meld.
2. Taste and adjust seasoning if needed. For extra brightness, squeeze some fresh lemon juice over the top.
3. Garnish with freshly chopped parsley and serve hot.
