01 - In a mixing bowl, combine the olive oil, lemon juice, smoked paprika, garlic powder, salt, and black pepper. Add the chicken pieces and toss until evenly coated. Cover and refrigerate for at least 15 minutes, or up to 2 hours for more pronounced flavor.
02 - Preheat a grill or grill pan over medium-high heat. If using skewers, thread the marinated chicken pieces onto them, leaving a small gap between each piece for even cooking.
03 - Place the chicken on the hot grill and cook for 3–4 minutes per side, turning once, until fully cooked through with light charring. Remove from the grill and set aside to rest briefly.
04 - While the chicken cooks, whisk together the mayonnaise, sour cream, Dijon mustard, minced garlic, parsley, and lemon juice in a small bowl. Season with salt and pepper to taste, then adjust as needed.
05 - Arrange the grilled chicken bites on a platter and serve immediately with the creamy garlic sauce alongside for dipping or drizzling over the top.
