We make this every year for Christmas breakfast. We now go to our daughter's home for Christmas. There is no need for the hostess to get up early to bake it in the morning. She assembles and bakes this early on Christmas Eve. In the morning, we cut it into squares and nuke it for a quick, easy, delicious breakfast. For low carb, simply replace the flour with soy flour.
1In a large bowl, combine cheeses. Sprinkle 1/2 of cheese mixture in a greased 13x9 baking dish. In a medium skillet, saute mushrooms, scallions and red bell pepper in butter until tender. Sprinkle vegetables over cheese. Arrange ham over vegetables and cover with remaining cheese.* Heat oven to 350. Lightly spoon flour into measuring cup and level off. In large bowl, blend flour, milk, parsley and eggs. Pour over layers in baking dish.
2Bake at 350 for 35-45 minutes or until mixture is set and lightly browned. Cut into squares and garnish with red bell pepper and parsley.
