Preheat your grill to medium-high heat. For oven cooking, preheat your oven to 450F/230C. If you’re grilling over a fire, make sure your coals have burned down quite a bit to avoid flare-ups.
Prepare the red bell peppers by cutting off the ends and removing the seeds. Slice them into lengthwise strips about 3/8 inches wide, allowing for even cooking and great texture.
Trim any fat or undesirable parts from the chicken breasts and cut them into lengthwise strips, aiming for about four strips per breast depending on size. This ensures they’ll cook evenly and absorb the flavors well.
Crumble the Feta cheese in advance so it’s ready to sprinkle over the chicken and peppers later.
Prepare four pieces of double-thick foil. Tear off a long piece and fold it in half to create a sturdy base that will hold up during cooking.
Lay the foil pieces on the counter and spray the center of each with non-stick cooking spray. This step is crucial as it prevents sticking—we don’t want our delicious meal to get caught in the foil!
Place one-fourth of the red pepper strips in the center of each piece of foil, followed by one-fourth of the chicken strips on top.
Drizzle a little olive oil over the chicken and sprinkle with salt, fresh ground black pepper, and the Greek seasoning. Don’t forget that both the Feta and seasoning have salt, so adjust accordingly.
Top each packet with one-fourth of the crumbled Feta, distributing it evenly for a rich, cheesy experience.
Now, seal the packets tightly but leave some room at the top to allow the Feta to melt without sticking to the foil. Lift the ends of the short sides up and fold over to seal, then fold the other two ends to secure everything inside.
Reduce the grill temperature to medium-low, or if using charcoal, pile the coals in the center and place the packets around the edges to cook. This indirect cooking method will help the ingredients steam perfectly.
Place the packets on the grill and let them cook for 15 minutes without turning. This is when the magic happens—let the heat do its work!
After 15 minutes, carefully open one packet to check if the chicken is fully cooked. It should be opaque and firm to the touch.
Serve the Greek Chicken Packets hot, and garnish with sliced green onions if desired. Enjoy unwrapping your personal bundle of joy!
For oven or campfire cooking, simply follow the same steps and adjust the cooking time as needed.
