Prepare the casserole up to the point of popping it into the oven to bake, then cover and refrigerate overnight. This is a great make ahead dish if you're hosting a brunch.
Low Country Breakfast Casserole
1 pound ground pork sausage, mil or hot, your choice
Brown sausage in a large skillet, stirring until it crumbles and is no longer pink, drain.
Bring water and salt to a boil in a medium saucepan; stir in grits. Return to a boil; cover, reduce heat, and simmer 5 minutes, stirring occasionally. Remove from heat; add 1 cup cheese, stirring until cheese melts. Stir in sausage, eggs, and remaining 3 ingredients.
Pour mixture into a greased 11 x7-inch baking dish; sprinkle with remaining 1/2 cup cheese. Bake, uncovered, at 350 degrees for 45 minutes or until set. Let stand 5 minutes before serving.
