"Authentic Italian pasta sauce is traditionally simmered for hours. But when you need a quick recipe sauce that’s close to the original, make this low-carb tomato sauce. All you need is olive oil, high-quality canned tomatoes, onion, garlic, and a handful of spices. Add it to zoodles, almond flour gnocchi, low-carb pasta, or use it for making Italian meatballs. It stores really well in the fridge and freezer if you end up with leftovers. Studies show that tomato sauces with olive oil are great for cardiovascular health, likely due to their antioxidants. Research also shows that the health benefits of tomatoes are greater when they are cooked than raw."

NotesCooking Tips - Be careful when heating extra virgin olive oil. It has a lower smoke point than many other plant oils, so overheating it can easily lead to burning and a bad-tasting sauce that’s also bad for your health. Simply, heat the oil over medium-high heat for half a minute before adding in the onions. Adjust the heat as necessary and sauté the onions until translucent. If you want a more flavorful sauce, cook this sauce for up to an hour uncovered.
