Liberty County public-school students won’t find high-calorie junk food favorites like chili cheese fries in their school cafeterias anytime soon, but they may find some new, healthier choices taste-tested by their peers.The school system’s nutrition department is giving students at all grade levels an opportunity to try some new recipes. Taste tests are being conducted this month, to determine which side items and vegetables should be introduced to students who eat school-cafeteria meals at breakfast and lunch. School nutrition coordinator Jessica O’Leary said about six to seven taste tests had been conducted so far, and expects to run about 20 more tests.
