To prepare the pork chops with stewed tomatoes recipe, you'll first need to prepare your ingredients. First, wash your potatoes and cut them into cubes. Then, in a large skillet, heat the olive oil over medium-high heat. Add the onion and cook until softened, about 5 minutes. Stir in the garlic and season with salt and pepper. Cook the onions and garlic for 1 minute, then add the tomatoes. Simmer, covered, for 30 minutes, stirring occasionally. Remove the pan from the heat and stir in 2 tablespoons of the thyme, 1 teaspoon of kosher salt, and 1 tablespoon of freshly grated Parmesan cheese. Taste the mixture and adjust seasonings, if necessary. Serve with sour cream.
