On a sunny July afternoon, a long line of students, ranging in ages from 4-18, listened eagerly as Boston Mayor Thomas Menino and representatives from USDA’s Food and Nutrition Service (FNS) and Boston Public School System kicked off for the Summer Food Service Program (SFSP). Cafeteria staff from Lila Frederick School in Dorchester, Mass. cooked and served a BBQ lunch for about 100 eligible SFSP students from the local neighborhood. On the menu: turkey hot dogs, grilled chicken, corn on the cob, fresh slices of watermelon, grape juice and fat free milk.
