01 - In a mixing bowl, whisk together olive oil, lemon juice, smoked paprika, garlic powder, salt, and black pepper. Add the chicken pieces and toss until well coated. Cover and let marinate for at least 15 minutes or up to 2 hours in the refrigerator for enhanced flavor.
02 - Preheat grill or grill pan to medium-high heat. If desired, thread the marinated chicken pieces onto skewers for easy handling.
03 - Cook the chicken bites on the grill for 3 to 4 minutes per side, or until fully cooked through and lightly charred. Remove from heat and set aside.
04 - In a separate bowl, combine mayonnaise, sour cream, Dijon mustard, minced garlic, chopped parsley, and lemon juice. Whisk until smooth. Season with salt and black pepper according to taste.
05 - Arrange grilled chicken bites on a serving platter and present with the creamy garlic sauce for dipping or drizzling. Serve immediately.
