Is there a food more humble yet universally adored than the sandwich?

And while one person’s go-to hamburger snack might be another’s katsu sando or chivito, there’s hardly a country on the planet that doesn’t turn to some type of bread with something stuffed inside it to cure a craving.

Traveling the world’s sandwiches is, in a way, like traveling the world.

To help narrow your choices for the sandwich to plan your next trip around, here are 25 of the world’s best sandwiches:

Bocadillo de jamón Ibérico, Spain

There are ho-hum ham sandwiches and then there’s this simple handheld featuring some of the world’s finest jamón, luxurious Iberian ham from acorn-fed pigs. The thinly sliced meat is piled on crusty bread that’s brushed or drizzled with extra virgin olive oil. Fresh tomatoes and perhaps some cheese can be added, but the ham is undoubtedly the star of this show.

Bánh mì, Vietnam

A culinary remnant of French colonialism, the baguette sandwich was reinterpreted to their own taste by the Vietnamese. Bánh mì are now sold from food carts on nearly every street corner in Ho Chi Minh City and across Vietnam and are widely loved well beyond the country’s borders.

The classic version is pork-based, starring chả lụa (Vietnamese-style pork roll), shredded pickled carrots, pickled daikon, cilantro leaves, mayonnaise and other ingredients. You can find variations with tofu and thinly sliced lemongrass chicken, too. The taste is crunchy, fresh, savory and utterly delicious.

Torta ahogada, Mexico

This “drowned” sandwich is the most popular street food in Guadalajara, the capital of Mexico’s Jalisco state.
