Creating BBQ Chicken Skewer Salad can be a straightforward and enjoyable process when following these simple steps:

1. Prepare Chicken: Cut the boneless chicken breast into 1-inch cubes for even cooking.
2. Marinate Chicken: In a bowl, combine olive oil, BBQ sauce, garlic powder, onion powder, smoked paprika, salt, and black pepper. Add chicken cubes, stirring to coat evenly. Let marinate for at least 10 minutes.
3. Preheat Grill: Preheat your grill or grill pan over medium-high heat.
4. Skewer Chicken: Thread the marinated chicken onto skewers, spacing them out evenly.
5. Grill Chicken: Place the skewers on the grill and cook for about 5-7 minutes per side, or until the chicken reaches an internal temperature of 165°F (75°C) and has nice grill marks. Remove skewers from the grill.
6. Prepare Vegetables: While the chicken is grilling, chop the red and yellow bell peppers, red onion, and cherry tomatoes.
7. Assemble Salad: In a large serving bowl, layer mixed salad greens, grilled chicken skewers, and chopped vegetables.
8. Top with Feta: If desired, sprinkle crumbled feta cheese over the salad for a creamy touch.
9. Serve with Dressing: Drizzle additional BBQ sauce over the salad or serve it on the side for guests to add their desired amount.
10. Garnish: Finish with chopped fresh cilantro on top for added freshness and flavor.
