Ronda Karbo shared a soy sauce marinade that we used on colorful beef and vegetable kabobs. "When our grill comes out tin the spring, this is the first recipe my family asks me to make," says the Russell, Minnesota reader. "You can also use this marinade on six pork chops or a large piece of round steak cut into serving-size pieces."
