"Greek salad is easily the most popular," said Allie Mack, GrubHub Seamless spokeswoman. "Mediterranean food is becoming such a lunch staple in downtown areas. It's definitely something that's trending" for lunch, she said. Traditionally, a Greek salad is made with tomatoes, sliced cucumbers, onion, feta cheese, and olives, seasoned with salt and oregano, and dressed with olive oil.

After Greek salad, the next two most popular lunches nationwide are garden salad and Caesar salad, respectively, and "house salad" also makes the Top 10. In addition, salads have moved beyond simple iceberg lettuce, cucumber and tomato, to include trendier items such as kale and arugula.
"We're seeing some healthier options," Mack said. "Despite cities having such a wide variety of different menu items and types, people are going for healthier options regardless of what cuisine they're ordering."
