It's a traditional breakfast staple that's enjoyed by millions of people every morning - and it's pretty hard to get wrong.
Served slightly crispy, on soft bread with lashings of brown sauce - or tomato, if that's more your thing - a bacon butty can make the difference between a good day, and a great one.
So it was unsurprising that one airline passenger was less than impressed with this poor attempt - dubbed the 'world's most disappointing bacon sandwich' - which was served to her on a recent flight.

The desperate attempt was shared by Liz Nugent whose friend ordered the “sandwich” while flying with Ryanair on Friday - Dublin Live reported.
Ms Nugent tweeted “My pal Aimee paid €5.50 (£4.70) for this ‘bacon sandwich @Ryanair today. I’m trying to figure out if it qualifies."
People shared their own thoughts on the sandwich.
One said: "This looks like whoever was making it got a little peckish."
Another said: "It's like a thought experiment in how far the concept of "bacon sandwich" can be whittled down before the thing falls apart. I'm enjoying Ryanair's new role as avant-garde philosophers."
A third added: "Surely this is grounds to sue for pain and distress!"
While another said: "Ryanair's T&Cs stretching to the rasher sandwich now too! "We reserve the right to withdraw the bacon in our bacon baguette.”
Luckily Aimee replied herself, saying that she did, in fairness, still eat the sandwich, and praised the flight's crew.
She said: "I also had a lovely flight and the cabin crew were class, I just found the sandwich humorous and slightly overpriced. Still ate it though!
"I doubt people will book a flight based on the quality of a sandwich to be fair!"
Ryanair has been contacted for comment.
