  • Combine the veggies with the basil, oregano, and ground pepper. Next add 3 tablespoons tomato paste and simmer for a few minutes longer, until the ingredients are thoroughly blended.
  • Following that, gently add one tablespoon of salt into a medium-sized saucepan or skillet and bring it to a boil. Next add the vegetable mixture and cook for at least one hour, stirring periodically.
  • After approximately an hour of cooking time, add tomato paste and salt to taste. Cook, covered, until all of the ingredients are well combined. If you like a thicker tomato sauce, cook it for a bit longer.

The length of time the sauce is cooked determines how thick and rich the finished result is.

If you want cheese with your pasta, grated Parmesan is often advised as a topping for tomato sauce since it enhances the richness of this wonderful meal.
