Low in fat, Mueller's Rigid Ziti spaghetti works well in both hot and cold spaghetti recipes. Mueller's Rigid Ziti Pasta is free of preservatives, artificial coloring and flavorings, and sodium and cholesterol. A timeless American design got a makeover. An iconic American tale: In 1867, Christian Mueller sold his handmade noodles door-to-door from his New Jersey residence. Generations of Americans have come to rely on Mueller's for traditional American pasta meals and noodle dishes, and nearly 150 years later, the brand is still the nation's favorite pasta. Once Mueller's Rigid Ziti Pasta has cooked in hot, boiling water, drain and serve with your preferred side dish or main course for even more deliciousness.
