Prepare the Dressing: Shake olive oil, balsamic vinegar, minced garlic, and 3/4 tsp salt in a jar until well combined.

Cook the Pasta: Bring a large pot of water to a boil with 2 tsp salt. Add pasta and cook for 2 minutes longer than package directions until very soft. Drain in a colander, return to the pot.

Flavour the Pasta: Pour 2/3 of the prepared dressing over the warm pasta. Stir well and let it sit for 15 minutes to absorb the flavors while it cools.

Marinate the Tomatoes: In a separate bowl, combine the chopped tomatoes (with their juices) and the remaining 1/3 of the dressing. Let sit for 10 minutes.

Combine: Pour the accumulated tomato juices into the pasta pot. Add the marinated tomatoes, finely sliced basil, and shredded parmesan. Gently toss everything together.

Season and Serve: Add 1/2 tsp salt to the tomato mixture and toss gently. Stir it all into the pasta. Serve immediately or chill for later.
