How to Make It
In a medium saucepan, bring the water and 3/4 teaspoon salt to a boil. Add the grits in a slow stream, whisking. Reduce the heat, cover, and simmer, stirring frequently with a wooden spoon, until the grits are very thick, about 20 minutes. Remove the saucepan from the heat and stir in the cheese.
Meanwhile, in a medium, nonstick frying pan, heat the oil over moderately low heat. Add the sausages and cook until they are just done, about 15 minutes. Remove the sausages from the pan. Add the tomatoes, the remaining 1/4 teaspoon salt, and the pepper to the pan. Cook until the tomatoes are just heated through, 1 to 2 minutes. Stir in the parsley.
Serve the grits topped with the sausages and the tomato sauce.
Vegetables such as okra, lima beans, or cooked greens would be perfectly in keeping with the Southern theme.
