School lunch providers say they want to offer healthier meals for kids but often don't have adequate funding to add vegetables and whole grains to the menu. Researchers at Temple's Center for Obesity Research and Education recently tested a program that added more healthy options in some Philadelphia schools, and registered dietitian Amy Virus says not all the changes were costly. "Amoroso actually makes a whole grain version of their roll," she said. "So, we were able to bring that in. We were able to stay with the same vendor and stay with a product that the kids liked."
