2 cans crushed tomatoes,
salt and pepper,
fresh basil/rosemary/oregano (any one or combo is fine),
fresh minced garlic,
red pepper flakes if desired,
Heat olive oil over medium flame in a saucepan. Add seasonings and fresh cut herbs and garlic. So you have everything but the tomatoes heating up in the olive oil. After you have all of that warmed up and the garlic cooked through, add the cans of tomatoes and heat through. Add additional seasonings as needed after adding the tomatoes. Allow it to cook while you cook your pasta, that's it. It tastes really fresh and light.
