Bocadillo de queso is a Spanish sandwich that consists of Spanish bread and slices of cheese. Due to the simplicity of the sandwich, both the bread and the cheese used for the preparation of this bocadillo variety must be of excellent quality.
The most common choice for bread is a Spanish-style baguette called barra de pan, while the selection of cheese includes various types of cheese such as Manchego cheese, queso fresco (fresh cheese), queso de cabra (goat cheese), Edam cheese, and blue cheese.
The bread is usually cut in half lengthwise, and it is often moistened with a drizzle of olive oil or rubbed with ripe tomato halves on the inside. Lettuce or rocket leaves, tomato slices, strips of roasted peppers, and slices of ham are some of the optional ingredients that may be added to the sandwich’s filling for added flavor and a more filling dish.
"A trip to Madrid should not be complete without a stop at the Jamón Museum. This is a great place to grab a quick snack or a cheap meal in true Madrid style. You'll find bocadillo de queso (cheese) among others here... in short, a good selection of bocadillos."
"El Sobrino is located in El Calero, just a few metres from the Calero Bakery, from which it gets its bread, which gives it permanent freshness. The result, a Bocadillo full of flavour, with good queso tierno, is a delight for the diner."
