Weekends Without Hunger Act This bill amends the Richard B. Russell National School Lunch Act to require the Department of Agriculture to establish a program to provide commodities, on a competitive basis, to public or private nonprofit institutions to provide nutritious food to at-risk children on weekends and during extended school holidays throughout the year (At-risk children are children who are eligible to receive free or reduced price meals under the Richard B. Russell National School Lunch Act or the Child Nutrition Act of 1966.)
