I bought one for $1.89.
Jack in the Box's Monster Taco lends itself well to delivering an enchilada-like experience. Between the greasy, partially soft and crunchy corn tortilla and paste-like meat filling, all you need is cheese and enchilada sauce to complete the experience.
The lettuce isn't usually found in/on an enchilada but is common enough to crunchy tacos and gives the dish some freshness as well as crispness.
