Pat the chicken breasts dry with paper towels to help the marinade stick better. Cut the chicken into nugget-sized chunks, about 1 to 1½ inches, keeping the pieces as similar in size as possible so they cook evenly.

In a medium bowl or large measuring cup, whisk together the dill pickle juice, milk, Greek yogurt, lemon juice, 1 tablespoon olive oil, kosher salt, black pepper, garlic powder, onion powder, smoked paprika, dried oregano, dried thyme, and sugar or honey (if using) until smooth and well combined. Taste and adjust salt if needed, keeping in mind the pickle juice is salty.
1/2 cup dill pickle juice, 1/4 cup milk, 2 tablespoons plain Greek yogurt, 2 tablespoons lemon juice, 1 tablespoon olive oil, 1 teaspoon kosher salt, 1/2 teaspoon black pepper, 1 teaspoon garlic powder, 1 teaspoon onion powder, 1 teaspoon smoked paprika, 1/2 teaspoon dried oregano, 1/2 teaspoon dried thyme, 1/2 teaspoon sugar or honey
Place the chicken pieces in a large zip-top bag or shallow glass dish. Pour the marinade over the chicken and toss gently to coat every piece. If using a bag, press out the excess air, seal, and massage to distribute the marinade. If using a dish, cover tightly. Refrigerate and marinate for at least 30 minutes and up to about 6 hours, with 1–3 hours ideal for best texture and flavor.

About 10–15 minutes before cooking, remove the marinating chicken from the refrigerator so it can lose some of the chill. Preheat a gas or charcoal grill to medium-high heat (around 400°F), or heat a large grill pan or cast-iron skillet over medium-high heat on the stove. Lightly brush the grill grates or pan with 1–2 tablespoons olive oil to prevent sticking.
1-2 tablespoons olive oil
If desired, thread the marinated chicken pieces onto metal or soaked wooden skewers for easier handling on an outdoor grill. This helps prevent smaller pieces from falling through the grates. Alternatively, leave the pieces loose, which works especially well for a grill pan or cast-iron skillet. Shake off any excess marinade so the pieces are coated but not dripping.
Place the chicken nuggets in a single layer on the hot grill or pan without crowding; cook in batches if necessary. Grill for 3–4 minutes per side, turning once, until nicely browned with light grill marks and the internal temperature reaches 165°F. If the chicken sticks when you try to flip it, give it another 30–60 seconds before turning so it can develop a good sear and release more easily.

Transfer the cooked grilled nuggets to a clean plate or platter and tent loosely with foil. Let them rest for about 5 minutes so the juices redistribute and the chicken stays moist.
Season the nuggets with a small pinch of additional salt and pepper if needed. Squeeze fresh lemon juice over the top for brightness and sprinkle with chopped parsley, if using. Serve warm with your favorite dipping sauces and any desired sides such as salads, veggies, potatoes, or rice.
