While the pasta is cooking, heat 1/2 cup olive oil in a 12-inch skillet or wide heavy saucepan over medium-high heat. Add minced garlic, cherry tomatoes, 1/2 teaspoon black pepper, 1/2 teaspoon sugar, and red pepper flakes (optional) to the pan. Cook, stirring occasionally, until the cherry tomatoes burst and release their juices, forming a sauce, for about 6-8 minutes.
