Just because it’s summer vacation doesn’t mean cafeteria workers aren’t cooking.Food service employees with the Warren County School System have been continuing their culinary training and were busy Thursday at WCHS learning new techniques for preparing high-quality food.“We’re trying to reduce the salt in our cooking and save the flavor,” said school system nutrition director Jean Wix. “We’re trying to promote healthy eating at a time when our society, because of our lifestyle and the convenience of fast food, doesn’t necessarily do so. But our school nutrition program does encourage healthy eating.”School lunches, for example, require a meat, vegetable, fruit, grain and bread to be served at every meal.
