You’ve heard of a plant-based diet, but have you heard of a bug-based one? Holly Branson met with the founders of Yum Bug and cooked up some tacos filled with… crickets! As Holly said: "I love how Leo and Aaron are passionately proving that bugs are sustainable superfoods that can be delicious too. The pair have invented a range of bug-based ‘mince’ and ‘strips’ that are popping up in restaurants and pubs all over London. As part of my Investing With Purpose series, I had the joy of cooking up a storm and tasting the grub myself, while chatting about the future of food and the key ingredients to launching a sustainable start-up.
