The U.S. Department of Agriculture will be testing Greek yogurt as a meat alternative in some federal school lunch programs this fall.  The protein-rich yogurt will be served in New York state, Arizona, Idaho and Tennessee schools to evaluate whether it's a cost-effective menu item.  Some members of New York's congressional delegation pushed for the pilot program to help boost the state's economy and dairy industry.

Some well-known brands of Greek yogurt are made in upstate New York.  The dairy item has grown into a six-billion-dollar industry in the U.S.
