Preheat oven to 400°. Toss cherry tomatoes with 1 tbs olive oil and season with salt and pepper. Place on a baking sheet and roast until blistered and cooked down, about 10 minutes. Remove and set aside to cool completely.
Meanwhile, bring a pot of water to a boil over high heat. Add pasta and cook according to package directions until al dente. Drain pasta, rinse with cold water to stop cooking and set aside.
