Brine the chicken: If your chicken did not come pre-brined from the store, you will want to take this short simple step first to assure that the juices are locked in and the chicken doesn't dry out on the grill.First, soak the chicken breasts in lukewarm salt water for at least 15 minutes. Then rinse the chicken off with some cold water, pat the chicken breasts dry with paper towels, and cut the chicken up into bite sized pieces. Next, cut the vegetables into about 1 inch pieces.
Seasn the chicken and vegetables: Drizzle the chicken and vegetables with olive oil, sprinkle on your desired dry seasonings (I used garlic pepper seasoning), and toss well in a bowl until everything is coated.
Thread the Skewers and Heat the Grill: Heat your grill up to medium-high heat. Thread the chicken and vegetables onto the skewers. I used a pattern of chicken, tomato, onion, red pepper, then green pepper, and repeated this pattern until the end of the skewer.Make sure you do not jam things too close together on your skewer. They will cook better if a little air can get in between the pieces.
On 350 degrees F, cook the chicken and vegetable skewers for about 6 or 7 minutes then turn and cook the other side 7 minutes. You can turn them more than once if needed. To keep the chicken from drying out we will occasionally spritz a little water on them as they are cooking, but make sure you don't put the charcoal out! If you are using the oven, cook them about 25 minutes on 450 degrees turning once halfway through. Your chicken should be golden brown and cooked all the way through. It may take a little practice to find that perfect balance between cooking the chicken enough but not overcooking it and drying it out. No one wants undercooked or overcooked chicken. The chicken is cooked when it reaches an internal temperature of 165 degrees F on an instant read meat thermometer and the juices run clear when a piece of chicken is cut.
Transfer the skewers to a clean plate and cover them loosely with aluminum foil to keep them warm. They are best served right away while the chicken is still warm and juicy. Garnish with fresh lemon wedges and a sprinkling of parsely if desired. Serve them with grilled or boiled corn on the cob and wild rice.
