Step 1

With a knife parallel to the work surface, cut the chicken breasts in half horizontally, creating 4 thin breasts. If necessary, place the breasts between two pieces of plastic wrap and pound each to about ½-inch thickness using a meat mallet or a rolling pin.

Step 2

Combine the olive oil, lemon juice, garlic, thyme, oregano, salt, and pepper in a large Ziplock bag. Add the chicken, seal the bag, and gently massage the marinade into the meat. Place the bag in the refrigerator and marinate for 3-24 hours.

Step 3

When ready to cook, oil the grates of a grill and preheat it to high. Grill the chicken breasts for 2-3 minutes per side, until the internal temperature reached 165°F.

Step 4

Transfer the chicken to a plate to rest for 10 minutes, then build sandwiches on rolls with your favorite toppings and serve.
