Insects as a source of protein was an idea put to the test on "try something new Tuesday", part of Keep Britain Tidy's "waste less, live more" week.
The unusual menu option was served at one of several events challenging people to think about the social and environmental impact of their relationship with food.
Keep Britain Tidy invited private, public and voluntary sector partners across the UK to stage a week of activities that would explore the idea of better food.
More than 70 partners rose to a different challenge each day of the week – from eating on the breadline on "thrifty Thursday" and going vegetarian on "meat-free Monday", to opting for the most abundant ingredients on "seasonal Sunday".
Keep Britain Tidy asked partners to reduce food waste, improve the nation's diet and promote a more sustainable food system.
It also hosted a conference to debate policy issues, with speakers from Tesco, WWF, FoodCycle and FareShare. The conference brought together more than 100 people to hear from experts about the links between food, waste and wellbeing and the need for collaborative change.
In addition, over 1,000 people took part in a series of partner events to help people think about sustainability in its broadest sense, such as food foraging walks and lunches made entirely from waste food.
Partners included the Feeding the 5,000 campaign and the Industry Council for Packaging and the Environment.
Keep Britain Tidy merged with the charity Waste Watch in 2011 and has since made Waste Less, Live More an annual event to communicate the message: what's good for the environment is good for people.
