Ruiz Foods has risen to the top. The nation's largest producer of frozen Mexican dishes, Ruiz offers more than 200 frozen foods, including burritos, taquitos, quesadillas, and tamales, under the El Monterey and Tornados brand names. The prepared convenience lineup can be found in grocery stores or on the menu of foodservice operators nationwide. Ruiz Foods manufactures its products at its main 300,000-sq.-ft. facility in Dinuba, California. To meet demand in the eastern and midwestern US, the company runs two more facilities based in Texas. To provide healthier food alternatives, the company has removed all trans fats from its El Monterey brand products. Ruiz is a third-generation family-owned business.
