A Jimmy Taco is the type of Taco you grew up having in America. Not a true south of the border taco, but now a staple of American-Mexican food.
The Jimmy Taco is always a hard shell taco with ground beef, lettuce,
shredded cheese, tomato and sour cream and/or salsa. Variations can be made. The Jimmy taco will eschew traditional Mexican
ingredients (crema, cotijia, cilantro) of the south of the border variety for
ingredients you will find in any state of the USA (sour cream, cheddar or "Mexican blend" pre-graded cheese as examples)
