To a large bowl, add the cherry tomatoes, shallot, garlic, basil, crushed red pepper flakes, lemon juice, & olive oil. Season with 1 ½ teaspoons kosher salt & ground black pepper as desired. Stir to combine well. Set aside to soak, marinate, & meld for at least 10-20 minutes. (Time permitting, a few hours yields maximum flavor, but if you’re prepping this at dinnertime, 10-ish minutes will do the trick just fine!)
At dinnertime, bring a large pot of water to a boil. Once boiling, generously salt the water. Add the capellini and cook to al dente according to package directions. Once al dente, drain the pasta & transfer directly to the bowl with the marinated tomatoes.
Add the shaved parmesan to the bowl with the marinated tomatoes & warm capellini. Toss to combine well. Taste & adjust seasoning as needed.
Immediately, topped with additional grated parmesan, chopped basil or parsley, &/or a sprinkling of crushed red pepper, as desired. Enjoy!
