Mix water, soy sauce, vegetable oil, lemon-pepper seasoning, and garlic in a deep bowl; add pork chops and toss to coat. Marinate in the refrigerator for at least 2 hours.

Preheat an outdoor grill for medium-high heat and lightly oil the grate.

Remove pork chops from the marinade and shake off excess; discard the remaining marinade.

Cook the pork chops on the preheated grill until no longer pink in the center, 5 to 6 minutes per side. An instant-read thermometer inserted into the center should read 145 degrees F (63 degrees C).

Serve hot and enjoy!
