Tomato and herb pasta sauce is a classic and versatile sauce that adds delicious flavor to any pasta dish. This sauce is typically made by sautéing onions and garlic in olive oil until they become fragrant and translucent. Then, ripe tomatoes are added, either fresh or canned, along with a variety of herbs such as basil, oregano, thyme, and parsley. The sauce is simmered on low heat, allowing the flavors to meld together and the tomatoes to break down and create a rich and thick consistency.
