This tomato sauce is one of a the standard recipes in our household that can be whipped up in less than 30 minutes. My son loves pasta and tomato sauce (this one!) in his lunchbox for school. I often make a big batch. That leaves room for variety and extension. Add some clam meat to make it a seafood tomato sauce over pasta, or add capers, olives and anchovies for a Puttanesca sauce. Thin it out with vegetable stock to make it a hearty tomato soup. The list is endless. The freshness that comes from the ingredients is unbeatable. No tomato sauce from a jar can ever taste like this.
1/4 teaspoon chili flakes (optional)
In a medium pan, heat olive oil over medium heat. Fry onions for a few minutes, then add minced garlic and fry for another few minutes. Stir in chopped tomatoes and tomato paste. Season with thyme, chili (optional), and sea salt. Cover with lid and simmer over low heat for about 15-20 minutes. Stir occasionally. Puree wit a blender to a smooth sauce or leave chunky.
