Magruder Inc., a seven-store retail grocery chain based in Rockville, Md., is now bringing in kosher lettuce products through Dole Food Co., said Stan Steppa, Magruder’s vice president and general manager.

“That has really exploded,” Steppa said. “We’re moving 80-150 cases a week. We can’t keep it on the shelf.”

Magruder has been bringing in kosher Italian blends, baby romaine and leafy romaine lettuce since May, he added.

“The stuff is beautiful, and we sell it for the same price that we sell the regular stuff for,” Steppa said. “That’s how we stay in business, because we dream up these things.”
