British Sandwich Week is perfectly placed at the beginning of picnic season. The summer months provide a great time to pack up some delicious sandwiches ahead of exciting days out. To celebrate British Sandwich Week and the summer season, we have crunched the numbers to find out which sandwich fllling is the UK's favourite.

Analysing the average number of searches per month, number of Instagram posts and TikTok views for each type of sandwich, the data revealed that a chicken sandwich is still the UK’s favourite sandwich, followed by egg sandwich and breakfast sandwich.

According to WRAP, the UK's Waste & Resources Action Programme NGO, around 9.5 million tonnes of food is wasted each year in the UK, of which 70% was intended to be consumed (the other 30% being the ‘inedible parts’ of food). By weight, household food waste makes up the lion’s share, accounting for 70% of UK food wastage.

A study by researchers at the University of Manchester in 2018 found that sandwiches containing a combo of pork meat (bacon, ham or sausages), cheese and prawns had the highest carbon footprint. Similarly, adding cheese to a vegetarian sandwich results in a carbon footprint comparable to, or even higher than, than that of some of the meat sandwiches.

Making your own sandwiches at home greatly reduces your carbon footprint. According to the study, the average carbon footprint of a home-made ham & cheese is around two times lower than that of a ready-made equivalent bought from a shop.
