allrecipes.com has five "Hamburger Pie" recipes. One has 4.5 stars. My TCU Women's Club cookbook has Hamburger Casserole... same, only different. Sadly, my Women of the United Methodist Church of Yoakum, Texas, cookbook is in L.A. and I'm in NYC. I say go with the 4.5 stars at allrecipes. it looks rilly good to me. xoxoSiddalee
