"This is tramezzino. We usually eat very stuffed sandwiches made with homemade bread in Italy but this is typical when you have 30 seconds and 3€ to have lunch. Sliced bread filled with deliciousness: ham and cheese."

"Sánduche de jamón y queso, aka a ham and cheese sandwich. This is peak Colombian. I think all Colombians have had this concoction in pretty much every possible situation… school breakfast, road trip, quick lunch etc. It never fails on flavor and simplicity!"

"A bacon sandwich, made with thick bacon, not the thin and streaky kind you see in the US. Oh, and to be extra British it has to be covered with plenty of brown sauce."

"The most popular sandwich in Portugal is no doubt the bifana. In fact, it's so popular, McDonald's even launched the McBifana here. Traditionally, it starts off with lightly-pounded pork steaks that have been marinated in a special garlic and spice concoction. The cutlets are then sautéed and served on distinctive crusty-on-the-outside, chewy-on-the-inside, floury Portuguese roll that has been slathered on one side with a mild deli-mustard."

"You can get a chicken fillet roll in every corner shop and it's always delicious. A crusty baguette, lettuce, mayo, breaded spicy chicken – and the rest of the toppings are up to you. It's the best lunch and also the best drunk food."
