Wendy’s is celebrating National Salad Month with an online scavenger hunt.

Consumers can search through Wendy’s social media channels to find answers to questions, with the chance of winning $25 gift cards, according to a news release from Dublin, Ohio-based Wendy’s.

One question, for instance, is “Some places claim the fruit on their salads is ‘fresh’, because that’s what it said on the can.” Searching Wendy’s website, Facebook, Twitter, MyWendy’s App, digital advertising or Instagram, consumers can find the answer: “We use fresh, hand-picked apples, strawberries and blueberries — not canned — on our Apple Pecan Chicken and Berry Almond Chicken Salads.”

Wendy’s sold more than 100 million salads in the U.S. in 2012. The chain also won the “Best Salads” category in Zagat’s 2012 fast-food survey, beating out Panera, Chipotle, Subway and other chains.
