Meanwhile, make sauce and cook pasta. In large Dutch oven, heat olive oil over medium heat and add garlic, sautéing for a few seconds, until sizzling, being careful not to burn it. Quickly add tomato passata, diced tomatoes, and salt, and bring to a boil. Reduce to a simmer, partially cover, and cook for 20 to 30 minutes. Cook pasta according to package directions and drain.
