Organic beans, rice, tofu: these foods feature prominently in the menu. In 2012 Chipotle purchased almost 7 million pounds of organic black beans. While Chipotle is not 100 percent organic, the organic label is an important piece of their growth strategy. It's great for business. Organic food sales in America â Chipotle is part of this â have risen by about twenty percent annually, making this the fastest growing slice of the food market.

Chipotle is the beacon of fast-casual food, with its focus on sustainability and high-quality products.
