Could I make pasta sauce wihtout using tomato paste/spaghetti sauce?

I would just go with the olive oil and fresh tomatoes and roasted garlic. Cut tomatoes in half and gently squeeze the juice out, then dice them. Cook and drain pasta and then toss in tomatoes, garlic and a little of the oil, letting the pasta cook the tomatoes. It will need, at least some oregano, fresh basil would be better. A gl of red wine or chianti.
