What have Mexican brought to the US?

Everything from baseball players, to salsa, to Pancho Villa. Mexico has had a dramatic impact on the United States and has had one for a long time. When Texas fought for its independence the Tejanos residing in Texas largely sided with Sam Houston and the Anglo-Rebels - the first vice-President of Texas was a Tejano 'Zapata' and also, coming from a nine year old, i have to guess that Mexicans brought piƱatas to America?
