Cut chicken into bite-sized pieces and season with salt, pepper, paprika, and Italian seasoning.
- Heat 1 tablespoon of olive oil in a large skillet over medium-high heat.
- Add the chicken and cook until browned and fully cooked, about 6–8 minutes. Remove from skillet and set aside.
- In the same skillet, heat the remaining olive oil and sauté garlic until fragrant.
- Add bell peppers, zucchini, broccoli, and onion. Cook for 5–7 minutes, stirring occasionally, until veggies are tender-crisp.
- Stir in cherry tomatoes and cooked chicken. Mix well and cook for another 2–3 minutes.
- Sprinkle shredded cheese over the top, cover the skillet, and cook just until the cheese melts.
- Garnish with chopped parsley or green onions if desired and serve warm.
