Great olive oil is key to making this simple pasta. We recommend california olive ranch brand olive oil, which is reasonably priced and found at most grocery stores. The tomatoes are charred on a sheet pan in the oven; shake the pan halfway through the cooking process to loosen any tomatoes that might be stuck to the pan as they cook and caramelize. Make this pasta with vegetable broth (instead of chicken broth) for a satisfying meatless meal.
