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 and cook for 5 to 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 of olive oil to the same skillet. Sauté minced garlic for 30 seconds until fragrant, being careful not to burn.
04 - Add zucchini slices to the skillet and cook for 3 to 4 minutes, stirring occasionally, until just tender-crisp.
05 - Add cherry tomatoes and red pepper flakes. Cook for another 2 to 3 minutes until tomatoes begin to soften and release juices.
06 - Return chicken to the skillet, nestling it among the vegetables. Top each chicken breast with sliced mozzarella. Cover skillet and cook for 2 to 3 minutes until cheese is melted and bubbly.
07 - Remove from heat. Drizzle with balsamic glaze and sprinkle with fresh torn basil. Serve immediately while hot.
