Season the chicken with 1 teaspoon extra virgin olive oil, salt, garlic powder, Italian seasoning and fresh pepper.: You will notice the oil creating a slight sheen on the surface of each chicken cutlet, which helps the dry seasonings adhere and promotes even browning. When you press the rub in with your fingertips you should feel the seasonings coating the meat rather than sitting in clumps. This step matters because a uniform seasoning layer ensures every bite has balanced flavor. A common mistake is piling seasoning into one spot instead of distributing it evenly, which can lead to bitter pockets or uneven crust development.
Preheat the grill to medium-high, clean and oil the grates to prevent sticking. If using a grill pan, heat on medium-high heat and spray with oil.: As the grill heats you should hear the soft hiss of moisture leaving the metal and smell the faint metallic warmth of a hot grate. A properly preheated surface will cause the chicken to sear on contact, creating those satisfying browned marks. Cleaning the grates removes residue that can stick and tear the meat, and oiling reduces adhesion so the cutlets release cleanly. Avoid placing meat on a cool grill, because it will stick and steam rather than sear.
Divide the arugula, 1 1/2 cups each on 4 plates.: When you arrange the arugula , fluff it gently so the leaves still have air and a light peppery chew. The greens will act as a cool bed for the warm chicken , so they should look lively and not compacted. This matters for texture contrast and presentation. A frequent slip is overdressing or packing the greens, which causes them to wilt under the warm chicken and lose their crispness.
Grill the chicken 2 to 3 minutes on each side, until cooked through then top with mozzarella. Cook 1 more minute, to melt then transfer to the 4 plates.: As the chicken hits the grate you should hear a steady sizzle and see immediate browning along the contact points. After 2 to 3 minutes the edges will show a golden rim and the surface will release from the grill without sticking, a sign it is ready to flip. Once both sides are seared and the internal juices run clear, place the thin slices of mozzarella on top; the cheese should begin to soften and wrinkle within a minute, becoming luscious but still yielding structure. This method preserves juiciness while achieving a mild char and a melty finish. Avoid overcooking, which dries the chicken and ruins the tender contrast with the cheese.
Top the chicken with cherry tomatoes and drizzle with balsamic glaze. Finish with fresh basil.: After transferring the warm chicken to the arugula beds, scatter the halved grape tomatoes so they nestle against the melted mozzarella . The tomatoes should glisten, and when pressed gently they will release a sweet, acidic note that livens the plate. A light, even drizzle of balsamic glaze will create glossy ribbons across the meat and greens, adding concentrated tang and sweetness that finishes the dish. Be mindful not to drown the plate in glaze, because too much can overpower the fresh ingredients and make the greens soggy.
Finish with fresh basil: Sprinkle the chopped basil leaves over each plate so their bright aroma lifts the assembled flavors. The basil should smell herbaceous and bright, offering an instant olfactory cue that the dish is ready. This final touch provides balance and a fresh contrast to the warm, savory components. Avoid chopping the basil too finely as it will bruise and lose aromatic intensity.
