In a gallon size Ziploc bag or large bowl, combine chicken and pesto; marinate for at least 1 hour to overnight, turning the bag occasionally. Drain chicken from the pesto.
Thread chicken and cherry tomatoes onto skewers; season with salt and pepper, to taste.
Preheat grill to medium high heat.
Add skewers to grill, and cook, turning occasionally, until the chicken is completely cooked through, reaching an internal temperature of 165 degrees F, about 10-12 minutes.*
Serve immediately, garnished with parsley, if desired.
Notes
An outdoor grill is not necessary. Too cold to grill outside? A cast iron grill pan can be used to get those favorited grill marks and charred flavor. These can also be baked at 400°F for 15-20 minutes (reaching an internal temperature of 165°F), brushing with some leftover pesto during the last few minutes of cook time.
Homemade pesto makes all the difference. While store-bought pesto can save a few minutes in the kitchen, homemade pesto will be much more fresh and vibrant, coming together in just 5 minutes. Homemade pesto also freezes beautifully!
Cut in uniform size. Cut all of the kabob ingredients in similar size pieces for a consistent bite, and to ensure even cooking.
Soak and freeze wooden skewers at the start of summer. Soak the skewers for at least 30 minutes (warm or cold water). Drain and store in a freezer bag for later use, using them straight from the freezer all season long.
Work in batches. An overcrowded grill or pan can lead to uneven cooking and poor browning. Work in batches to maintain high heat for a good sear and crispy crust on each chicken skewer.
Use an instant-read thermometer for the most accurate results. The internal temperature should reach 165°F.
Let your meat rest. Let your chicken kabob rest for at least 5 minutes prior to serving, allowing the juices to redistribute – this will allow for maximum flavor and juiciness.
Reheat in the oven. Leftover chicken can be rubbery when reheated. For best results with leftovers, reheat in the oven at 350°F, covered in aluminum foil until warmed through.
Mix it up. Swap out the tomatoes for different vegetables such as zucchini, mushrooms, red onion or bell peppers. You can also serve these as skewers, salad mix-ins, or grain bowls. The possibilities are endless.
