The Japanese burger chain, Freshness Burger, will start selling a new healthy burger from Sept 10. It is a vegetarian burger that uses a whole gigantic mushroom as a patty instead of a meat one.

The gigantic mushroom cannot be mass-grown so the number of burgers sold will be limited per day. In addition to the mushroom, the sandwich includes lettuce, tomato, onion, balsamic sauce, and egg-free vegetable mayonnaise.

Price: To be announced.
