This hamburger patty is made with a mushroom-based meat analogue. Accounting for more than half of its ingredients are four types of Japanese mushrooms: brown beech mushroom, king oyster mushroom, shiitake mushroom, and enoki mushroom. No animal-based ingredients are used. This product is recommended for vegetarians as it has been prepared using only plant-based ingredients without any additives. It has a low caloric content of only 90.4kcal per piece (80g). As it is mushroom-based, it is rich in dietary fiber. This product is also rich in ornithine, which is said to be effective for combating hangovers and improving sleep quality, as well as chitoglucan, which is believed to be effective for weight loss. To serve, simply add some oil to a frying pan and heat up the patty for around 5 minutes in the pan at a temperature of around 160°C while flipping it occasionally to prevent it from burning.
