01 - In a mixing bowl, combine olive oil, BBQ sauce, smoked paprika, garlic powder, salt, and black pepper. Add the chicken cubes and toss to coat evenly. Let marinate for at least 15 minutes.
02 - Preheat a grill or grill pan to medium-high heat. Thread the marinated chicken cubes onto skewers, leaving a small gap between each piece for even cooking.
03 - Place skewers on the hot grill and cook for 10-12 minutes, turning occasionally and brushing with extra BBQ sauce, until the chicken is cooked through and lightly charred.
04 - While the chicken grills, arrange the mixed greens, red and yellow bell peppers, cherry tomatoes, red onion, avocado, and cucumber in a large serving bowl or on a platter.
05 - In a small bowl, whisk together olive oil, apple cider vinegar, honey, Dijon mustard, salt, and pepper until well combined and slightly emulsified.
06 - Place the grilled chicken skewers over the assembled salad, drizzle generously with dressing, and serve immediately.
