Creating these savory Lemon Herb Chicken Skewers is straightforward. Just follow these simple steps:

1. Prepare the Marinade: In a large mixing bowl, combine olive oil, lemon juice, lemon zest, minced garlic, parsley, thyme, rosemary, salt, and black pepper. Whisk until well blended.
2. Marinate the Chicken: Add the cubed chicken breast to the marinade and toss to coat. Cover the bowl and refrigerate for at least 30 minutes.
3. Prepare the Skewers: If using wooden skewers, soak them in water for at least 15 minutes to prevent burning on the grill.
4. Assemble the Skewers: Thread the marinated chicken cubes onto the skewers, alternating with bell pepper and onion pieces if you’re using them.
5. Preheat the Grill: Set your grill to medium heat.
6. Cook the Skewers: Place the skewers on the grill and cook for about 10-15 minutes. Turn occasionally until the chicken is fully cooked and has nice grill marks. The internal temperature should reach 165°F (75°C).
7. Serve: Remove the skewers from the grill and let them rest for a few minutes before serving.
8. Garnish: Optionally, squeeze some fresh lemon juice over the skewers before serving for an extra zesty kick.
