01 - Pat chicken breasts dry with paper towels. Season both sides generously with salt, pepper, and Italian herbs, pressing seasoning into meat to adhere.
02 - Heat 1 tablespoon olive oil in a large skillet over medium-high heat until shimmering. Add chicken breasts and cook for 5-6 minutes per side until golden brown and internal temperature reaches 165°F. Transfer to a plate and tent with foil to keep warm.
03 - Add remaining tablespoon olive oil to the same skillet. Sauté minced garlic for 30 seconds until fragrant, being careful not to burn.
04 - Add zucchini rounds to the skillet. Cook for 3-4 minutes, stirring occasionally, until just tender-crisp and lightly golden.
05 - Stir in cherry tomatoes and red pepper flakes. Cook for another 2-3 minutes until tomatoes begin to blister and soften slightly, releasing their juices.
06 - Return chicken to the skillet, nestling pieces among the vegetables. Top each chicken breast with mozzarella slices. Cover skillet with lid and cook for 2-3 minutes until cheese is melted and bubbly.
07 - Remove from heat. Drizzle entire dish with balsamic glaze and sprinkle generously with torn fresh basil leaves. Serve immediately while hot.
