01 - Whisk together olive oil, lime juice, chili powder, cumin, smoked paprika, garlic powder, onion powder, salt, and black pepper in a bowl. Add chicken breasts and turn to coat thoroughly. Let marinate for at least 10 minutes while preparing other components.
02 - Preheat grill or grill pan to medium-high heat. Grill marinated chicken for 6–7 minutes per side until fully cooked, reaching an internal temperature of 165°F. Transfer to a cutting board and let rest for 5 minutes, then slice into strips.
03 - Arrange mixed salad greens on a large serving platter or individual plates. Top with sliced red and yellow bell peppers, thinly sliced red onion, avocado slices, and halved cherry tomatoes.
04 - Whisk together olive oil, lime juice, honey, ground cumin, salt, and pepper in a small bowl until emulsified and smooth.
05 - Arrange warm sliced chicken strips over the prepared salad. Sprinkle with fresh chopped cilantro. Drizzle dressing generously over the entire salad just before serving.
