A taco is a sort of one-piece sandwich made by folding a thin flat piece of bread, often corn bread, around vegetables, meat, and sometimes dairy products. Tacos originated in Mexico and are madly popular as snack food in the United States. There are restaurants whose whole theme is "taco bar," but it's also easy to make tacos at home.
Traditional tacos include spicy ground beef, lettuce, tomato, cheese, and/or sour cream. There are various authentic Mexican recipes for grinding and mixing your own spices, but so far as I know most people in the U.S. buy premixed "taco seasoning" packets.
Tacos sold without special identifying labels can also include chopped onion, cucumber, parsley, cilantro, guacamole, and/or peppers.
Taco restaurants have been selling chicken tacos for a long time. These are made with chunks of spicy grilled chicken, vegetables, and often cheese.
Then there's a new fad for fish tacos, which are, of course, made with chunks of cooked fish and/or shellfish, vegetables, and sometimes cheese or guacamole.
What do you put in your tacos?
