Greek Island Chicken Shish Kebabs

The Ingredients that you will need are the following :

¼ cup olive oil 
¼ cup lemon juice 
¼ cup white vinegar 
2 cloves garlic, minced 
1 teaspoon ground cumin 
1 teaspoon dried oregano 
½ teaspoon dried thyme 
¼ teaspoon salt 
¼ teaspoon ground black pepper 
2 pounds skinless, boneless chicken breast, cut into 1 1/2-inch piece 
6 eaches wooden skewers 
2 large green or red bell peppers, cut into 1-inch pieces 
1 large onion, quartered and separated into pieces 
12 eaches cherry tomatoes 
12 fresh mushrooms   

How to Prepare. 

The steps are the following : 

1. Whisk the olive oil, lemon juice, vinegar, garlic, cumin, oregano, thyme, salt, and black pepper together in a large glass or ceramic bowl. Add the chicken and toss to evenly coat. Cover the bowl with plastic wrap; marinate in the refrigerator for at least 2 hours.
2. Soak wooden skewers in water for about 30 minutes before use.
3. Preheat an outdoor grill for medium-high heat; lightly oil the grate.
4. Remove the chicken from the marinade and shake off excess liquid. Discard the remaining marinade. Alternately thread pieces of the marinated chicken with pieces of bell pepper, onion, cherry tomatoes, and mushrooms onto the skewers.
5. Cook the skewers on the preheated grill, turning frequently until nicely browned on all sides, and the chicken is no longer pink in the center, about 10 minutes.
