While pasta cooks, heat 2 tablespoons of olive oil in a large sauté pan. I use a 12 inch lidded All-Clad sauté pan.
Add the onions to the oil and cook for about 5 minutes, then add garlic, tomatoes and salt to taste - consider the amount listed above a suggestion.
Pour the tomato mixture over the drained pasta and toss in the basil and parmesan cheese.
