Into a large glass bowl or jar, pour the oil and add the basil, garlic and parsley. Core and cut the tomatoes in half and gently squeeze out the seeds. Dice the tomatoes. Add them with the salt and pepper to the jar or bowl. Cover tightly with plastic wrap and refrigerate for 2 days or leave at room temp for several hours to use the same day. Cook pasta according to directions and toss with butter. Just warm the sauce and toss with hot pasta. ***This is great when it10th too hot to cook and those tomatoes are just begging you from the garden. Make a big batch and keep it on hand for company.
