Lightly grease a 9 x 13 inch pan. Place bread cubes in pan. Arrange cooked turkey and mushrooms over bread. Whisk together milk, eggs and seasoning. Pour over bread, turkey and mushrooms. Cover pan and refrigerate overnight. Remove covering and bake at 350°F for 30 minutes. Remove and spread shredded cheese over the top and bake for another 30 minutes. Strata should be done when a knife inserted comes out clean. Serve warm.
* leftover Thanksgiving turkey works well!
