Start by preparing your marinade: in a mixing bowl, whisk together lemon juice, minced garlic, chopped oregano, and chopped parsley. Slowly drizzle in olive oil while whisking until well combined.
Add the chicken chunks to the marinade, ensuring each piece is thoroughly coated. Cover and refrigerate for 2 to 4 hours to deepen the flavor.
While the chicken marinates, prepare your vegetables: cut the bell peppers into chunks and the red onion into thick wedges. Thread the chicken, peppers, and onions alternately onto skewers, leaving some space between pieces for even cooking.
Preheat your grill to medium-high heat. Brush the grill grates with a little oil to prevent sticking.
Place the skewers on the grill and cook for about 12-15 minutes, turning every 3-4 minutes to achieve an even char and caramelization. You’ll hear a sizzling sound and see juices bubbling as they cook.
Brush the skewers with additional olive oil during grilling for extra moisture and shine. Keep an eye out for a golden-brown caramelized exterior.
Once cooked through (internal chicken temperature should reach 165°F), remove the skewers from the grill and let rest for a couple of minutes. The aroma of herbs and grilled meat will fill the air.
Serve the kabobs hot off the grill, garnished with a sprinkle of fresh parsley if desired. Enjoy the smoky, juicy bites with your favorite sides.
