According to the research, which was carried out by British Sandwich Week, we munch our ways through a huge 250 million butties a week. This equates to five each - although some feast on a massive 12!
When it comes to our fave fillings, cheese and pickle was voted number one, while tuna mayo earned second place and BLT came in at number three.
Other classic combinations included egg mayo, cheese and onion, and ham.
Surprisingly, neither prawn mayo, beef or turkey fillings appeared in the top 10.
And one in five of us aren't happy with simply bread and filling - they add crisps to their favourite lunch.
We're hungry just thinking about!
