Step 1: Prepare the Marinade

In a large bowl, combine 1/4 cup olive oil, 3 tablespoons fresh lemon juice, 3 cloves minced garlic, 1 tablespoon dried oregano, 1 teaspoon ground cumin, 1 teaspoon paprika, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Mix well to create a marinade.

Step 2: Marinate the Chicken

Add the cubed chicken pieces to the marinade, ensuring they are well-coated. Cover the bowl and refrigerate for at least 30 minutes, preferably up to 2 hours for maximum flavor.

Step 3: Preheat the Grill

Preheat your grill to medium-high heat (about 375°F to 450°F).

Step 4: Assemble the Skewers

Thread the marinated chicken pieces onto the soaked wooden skewers, leaving a little space between each piece for even cooking.

Step 5: Grill the Skewers

Place the chicken skewers on the preheated grill. Grill for about 10-12 minutes, turning occasionally, until the chicken is cooked through and has a slight char. Once ready, remove the skewers from the grill.

Step 6: Serve

Serve with warm pita bread, tzatziki sauce, and fresh vegetables such as tomatoes, cucumbers, and red onions.
