Lava sauce dates its origins back to September 2008, with its introduction in the Volcano Taco. Users across the country praised its roll-out, design, and flavor. In May 2009, the Volcano Menu expanded to include the Volcano Burrito and the Volcano Nachos, which incorporated Lava sauce and generated even more praise for the company. Lava sauce was a strong selling point for the Volcano Menu, and with the passage of time came a decrease in sales. Among the reasons was a leaning-away from fast food in general.
