While in Italy I learned to make a simple yet flavorful Sicilian style tomato sauce. It was taught to me by the world renowned "Chef Mimmo" of the amazing Osteria Bacchus in the hills of Sant'Ambrosio. During his epic 6 hour cooking class, he was adamant that this recipe is the base for every Italian tomato sauce - and that there shouldn't be any tampering. He considers it a culinary crime if you add anything else! (And don't even get him started on pineapple as a pizza topping...)
Heat a pot to medium high heat and add the olive oil.
Add the onions to pot, and sauté for a few minutes until softened.
Add the basil, sugar, salt, and strained tomatoes. Mix well. Increase heat to high until the mixture boils. Then turn down the heat, cover the mixture and let simmer for 60-90 minutes.
Taste - add bit more salt if needed.
In my opinion, nothing beats a freshly homemade tomato sauce. Tomatoes are a very high source of vitamin C and lycopene - an anti-oxidant known to fight breast and prostate cancer. What’s great is that olive oil not only brings out the flavor of the tomatoes and the garlic, but it also increases the absorption of the cancer fighting lycopene and powerful immune boosting properties of the garlic.
