The only thing I changed from my other recipe was the topping - here you go.
Corn meal mush (I know sounds so attractive)
3/4 cup cornmeal
1/2 teaspoon salt
2 cups cold water
1 tablespoon butter
Stir cornmeal and salt into water in a pan and cook until thick stirring often. When thickened after about 15 min or so mix in the butter. Lay in strips down the hot casserole and bake.
