Honey Soy Tilapia

Mix the honey, soy sauce, balsamic vinegar, and garlic together in a bowl. Place the tilapia fillets in the mixture; allow to marinate in refrigerator at least 30 minutes.
Preheat an oven to 350 degrees F (175 degrees C). Spray a baking dish with cooking spray.
Remove tilapia from marinade, and discard the marinade. Place fillets into the prepared baking sheet, and sprinkle the black pepper over the fish.
Bake in the preheated oven until the fish flakes easily with a fork, 15 to 20 minutes.
