Avocado toast remains in the spotlight, but some concepts are tapping into the trend with other veggies. True Food Kitchen turns to asparagus, a vegetable closely linked to spring, to tempt winter-weary customers. This sandwich is a build of grilled asparagus, roasted cipollini onion, green garbanzo, tahini and hemp seed. True Food puts a laser focus on seasonality in developing its menu and tends to explore more unusual vegetables, such as green garbanzos and cipollinis. The plant-forward combination appealed to 72% of potential purchasers for its uniqueness in Technomic’s survey.
