Sea salt to taste

Instructions
In a medium saucepan, heat the olive oil over medium-low heat. Add the onions and sauté gently until softened, about 10 minutes. Add the garlic and cook another minute.
Add the tomatoes and tomato paste with 2 generous pinches of sea salt and bring to a simmer. Cover the sauce, lower the heat and simmer for about 20 minutes.
Puree about half the sauce with an immersion blender or pass through a food mill. (You can also blend half the sauce in a blender or food processor. Put the sauce back into the saucepan.)
Add the basil and simmer for another 5 minutes or longer, if you have the time. Taste and adjust seasoning.
Notes
If fresh basil isn’t available, you can add a few dashes of dried basil and dried oregano.
