Queso fundido is a tasty Mexican comfort food dish that is typically served as an appetizer. It consists of pieces of chorizo, tomatoes, onions, poblano peppers, and gooey, stringy melted cheese. The dish is often prepared tableside in restaurants, where it is flambéed and presented bubbling hot in small casserole dishes.

Queso fundido is traditionally spooned onto soft corn tortillas so that it could be eaten individually, as the dish is typically shared between groups of people, making it a great party food as well. It originated in northern Mexico, where it was originally prepared as a campfire dish.
