Bring 4 quarts of water to a boil in a large pot. Drop the tomatoes into the water and leave for 20 seconds. Then drain and cool under cold water. Peel, core, and seed the tomatoes, and coarsely chop.
Heat the oil in a large skillet. Add the chopped tomatoes, salt, and pepper. Simmer over medium heat for 15 minutes. Add the garlic, and cook another 5 minutes. T
