A taco is a traditonal mexian dish 
Yes it is.  And that are so many ways it can be made.  It has been around for years
Very true , tacos can be made with a variety of fillings such as , beef, pork, chicken, even seafood
I really like breakfast tacos.  Normally it is filled with eggs, cheese and meat
Yeah breakfast tacos are great.  Another fact about breakfast is that the old english word for dinner means break a fast and was the first meal eaten in the day until its meaning shifted
I did not know that but it makes sense.  
Yeah, we also have found that from archeological evidence we know there was an early reliance on cereal grains 
I do enjoy cereal.  I like the old school cereals such as Cheerios and Wheaties.
