01 - Preheat your grill to medium-high heat, approximately 400°F.
02 - In a small bowl, combine the olive oil, smoked paprika, garlic powder, onion powder, sea salt, black pepper, and lime juice. Mix thoroughly until well blended.
03 - Pat the chicken breasts dry with paper towels. Brush both sides of each breast evenly with the prepared marinade.
04 - Place the chicken on the preheated grill and cook for 6 to 7 minutes per side, until the internal temperature reaches 165°F and juices run clear. Remove from the grill and let rest for 5 minutes.
05 - While the chicken grills, gently toss the diced avocados, quartered cherry tomatoes, red onion, cilantro, lime juice, sea salt, black pepper, and jalapeño if using in a medium bowl. Combine carefully to keep the avocado intact.
06 - Serve each grilled chicken breast topped generously with the fresh avocado salsa.
