Chipotle has had a challenging few months, with the Centers for Disease Control and Prevention last month concluding its investigation into E. coli incidents associated with the restaurant chain.

"It's a health and wellness play," Cramer said. "They bought a huge amount of stock back at $500" and "Chipotle is winning."

The company has launched an aggressive marketing and promotional campaign to win back customers. Chipotle plans to spend $50 million in the first quarter for the marketing campaign, which will continue through the summer.
