Sprinkle pork with salt and pepper. Cook, in batches, in hot oil in a large skillet over medium-high heat 3 minutes on each side or until done. Transfer pork to a wire rack in a jelly-roll pan, and keep warm in a 200° oven.
Add shallots and thyme to skillet; sauté 1 minute or until tender. Stir in wine and pepper jelly until smooth. Stir in peach and tomato, and cook, stirring often, 2 to 3 minutes or until thoroughly heated. Add salt and pepper to taste. Pour sauce over pork, and serve immediately with grits.
The peach sauce makes this recipe outstanding! This recipe is simple and fast enough to make on a weeknight. I warmed the leftover grits with a pad of butter for a delicious breakfast the next morning.
