Mushroom Monday is a monthly dehydrated mushroom delivery service that promotes a flexitarian diet with the aim of reducing carbon emissions from meat consumption. Each delivery box contains four packs of dried mushrooms and a unique monthly cookbook for returning customers to add to their mushroom cookbook collection. The idea is to gradually introduce omnivores (people who eat both meat and plants) to a flexitarian diet (a primarily plant-based diet with occasional meat consumption) which significantly helps reduce greenhouse gas emissions produced by the food system and promotes sustainable farming and consumption. By initiating a “do it yourself” experience, I hope to create a positive association with a meatless diet and develop a habit of consuming plant-based meals.
