Cargols a la llauna is a traditional dish originating from Catalonia. It's made with a combination of snails, mayonnaise, and garlic. The snails are grilled in their own shells for a few minutes, then served with garlic and mayonnaise sauce. The snails are then traditionally dipped in the sauce.

Every year, 200,000 people come to Lleida for the Aplec del Cargol (which can be translated as snail gathering) to enjoy snail-based specialties.
