HOT PASTA with COLD SAUCE

Fifteen years ago when I was living in Paris, one of my friends surprised me with a birthday dinner. She made a pasta dish that was truly memorable. It was a hot pasta served with a cold/room temperature sauce of fresh tomatoes, basil, garlic, parmesan cheese, garlic salt and other things. I have misplaced the recipe.

This recipe was apparantly the hottest thing in Fairfield Connecticut, where this girlfriend was from. Everyone made it, talked about it, and raved.

If anyone can help recreate this, I would be most appreciative.
