01 - Pat chicken breasts dry and season both sides with salt, pepper, and Italian herbs.
02 - Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add chicken and cook for 5–6 minutes per side, or until golden and cooked through. Transfer to a plate and cover to keep warm.
03 - In the same skillet, add the remaining tablespoon of olive oil. Sauté garlic for 30 seconds until fragrant.
04 - Add zucchini and cook for 3–4 minutes, stirring occasionally, until just tender.
05 - Add cherry tomatoes and red pepper flakes (if using). Cook for another 2–3 minutes, until tomatoes begin to soften.
06 - Return chicken to the skillet, nestling it among the vegetables.
07 - Top each chicken breast with sliced mozzarella. Cover the skillet and cook for 2–3 minutes, until the cheese is melted.
08 - Drizzle with balsamic glaze, sprinkle with fresh basil, and serve immediately.
