What is the main protein in a cubano sandwich?

The main protein in a cubano sandwich is pork. Traditionally, a cubano features layers of moist, seasoned roast pork, which is often combined with other meats such as ham, Swiss cheese, pickles, and mustard, all served on Cuban bread. The use of pork is a defining characteristic of the sandwich, and its flavors are intensified through the cooking process, making it a delectable choice for many.

While other proteins like roasted chicken or tuna are popular in various dishes, they do not align with the traditional ingredients of a cubano sandwich. Lentils, being a vegetarian option, do not fit into this specific sandwich's context, as the cubano is primarily known for its savory, meat-centric profile. Hence, the prominence of pork in a cubano is what makes it authentic to the dish's cultural roots and culinary essence.
