<human>:  How can I create an Italian tomato sauce from scratch?
<bot>: To create an Italian tomato sauce from scratch, you will need to start by sautéing some garlic and onion in a pan with a little extra-virgin olive oil. Once these are softened, add a can of diced tomatoes and any desired herbs, such as oregano, basil, or parsley. Allow the sauce to simmer for at least 30 minutes, adding a pinch of sugar to give it a more balanced flavor. Finally, add salt and pepper to taste and serve hot over your favorite pasta. Buon appetito!
