How to Make It
In a large skillet, heat the olive oil. Add the sausages and cook over moderate heat, turning occasionally, until browned but not cooked through, about 5 minutes.
Add the water to the skillet. Cover and cook until the water is nearly evaporated and the sausages are firm, about 7 minutes. Add the apples and fennel seeds and cook, stirring occasionally, until the apples are tender and browned, 8 minutes. Stir in the vinegar and season with salt and pepper. Serve in bowls atop the Cheesy Grits.
