01 - Soak wooden skewers in water for 15 minutes if using. In a bowl, toss chicken cubes with olive oil, BBQ sauce, smoked paprika, garlic powder, salt, and black pepper. Thread chicken, bell peppers, and red onion alternately onto the skewers.
02 - Preheat grill or grill pan over medium-high heat. Grill the skewers for 10-12 minutes, turning occasionally and brushing with extra BBQ sauce, until chicken is cooked through and slightly charred.
03 - While the skewers cook, arrange salad greens, cherry tomatoes, cucumber, avocado, and feta on a large platter.
04 - Whisk olive oil, apple cider vinegar, honey, Dijon mustard, salt, and pepper together to make the dressing.
05 - Drizzle dressing over the salad and toss gently to combine. Remove the chicken skewers from the grill and place on top of the salad. Serve immediately.
