1. Prepare the Chicken for Grilling: Pat the chicken breasts dry with paper towels. In a small bowl, combine 1 tablespoon of olive oil, smoked paprika, garlic powder, onion powder, black pepper, and salt. Rub this mixture evenly over both sides of the chicken breasts. Let the chicken sit at room temperature for about 10 minutes while you prepare the grill and salsa. This brief rest helps the flavors meld and the chicken cook more evenly.

2. Preheat Your Grill: Preheat your outdoor grill to medium-high heat (around 400-450 F or 200-230 C). Make sure the grates are clean to prevent sticking. If using an indoor grill pan, heat it over medium-high heat until it’s very hot. A well-heated grill creates those beautiful sear marks and ensures juicy chicken.

3. Assemble the Fresh Peach Salsa: While the grill heats, combine the diced peaches, finely diced red onion, chopped fresh cilantro, minced jalapeño (if using), fresh lime juice, 1 tablespoon of olive oil, and a pinch of salt in a medium bowl. Gently toss everything together until well combined. Taste and adjust seasoning if needed; you might want a little more lime juice or salt depending on the sweetness of your peaches. Set the salsa aside.

4. Grill the Chicken to Perfection: Once the grill is hot, place the seasoned chicken breasts directly on the grates. Close the lid and cook for 6-8 minutes per side, or until the internal temperature reaches 165 F (74 C) when measured with an instant-read thermometer inserted into the thickest part of the breast. The chicken should have nice grill marks and be opaque throughout. Avoid overcooking, as this can lead to dry chicken.

5. Rest the Cooked Chicken: Once cooked, transfer the grilled chicken breasts to a clean cutting board. Tent them loosely with aluminum foil and let them rest for 5-10 minutes. This resting period is crucial as it allows the juices to redistribute throughout the meat, resulting in much more tender and flavorful chicken.

6. Slice and Serve: After resting, slice the chicken breasts against the grain into thick pieces or serve them whole. Top each piece generously with the fresh peach salsa. Serve immediately and enjoy the vibrant flavors!
