If the sundried tomatoes are dried, hydrate them by immersing them in warm water until soft and tender. If you are using deli style in flavoured oil them no need to hydrate and also include the oil!!
Add the tomatoes, minced garlic, basil, pine nuts and chopped onion and blitz until blended.
Add the tomato paste/puree, tomatoes, red wine and vinegar and blend again until it reached the consistency you enjoy.
Finally add the parmesan cheese and olive oil and stir in well. Taste and season accordingly.
Add a few small basil leaves as garnish and serve.
