Heat a saucepot to medium high. Add olive oil and chopped, diced and minced vegetables except the tomatoes and sauté mixture for 5 minutes, or until soft. Add diced tomatoes, tomato paste and fresh basil. Simmer 20 minutes, or until liquid in saucepot thickens to desired consistency.
Run through a food mill if smooth sauce is desired. Season with salt and pepper. Reserve boiling water that cooked the pasta and use, if needed, to thin and adjust sauce consistency.
