Creating Greek Chicken Souvlaki can be a smooth process if you follow these steps:

1. Prepare the Marinade: In a medium bowl, whisk together the olive oil, lemon juice, minced garlic, oregano, salt, black pepper, and paprika.
2. Marinate the Chicken: Add the cubed chicken to the marinade, ensuring each piece is well-coated. Cover and refrigerate for at least 30 minutes, and up to 1 hour for deeper flavor.
3. Preheat the Grill: While the chicken marinates, preheat your grill to medium-high heat.
4. Prepare the Skewers: Thread the marinated chicken onto skewers, making sure to leave space between pieces for even cooking.
5. Grill the Chicken: Lightly oil the grill grates and place the skewers on the grill. Cook for about 10-15 minutes, turning occasionally until the chicken is fully cooked and has nice grill marks.
6. Check Doneness: The internal temperature of the chicken should reach 165°F (75°C). Remove from the grill and let rest for a few minutes.
7. Serve: Once rested, remove chicken from the skewers. You can serve it as is or chop into pieces for salads or wraps.
