I made this for an outdoor dinner in July when it was too hot to eat anything warm. The shrimp are grilled, the pasta is cooled, and the whole dish is served at room temperature or chilled. Short gluten-free pasta tossed with grilled shrimp, asparagus, cherry tomatoes, sun-dried tomatoes, minced shallots, garlic, red chili flakes, olive oil, and balsamic vinegar. The balsamic vinegar is what surprised me.
