What should I bring to a Carne Asada?

From my experience, usually, the guests don't have to bring anything since the hosts will always provide everything. I would say don't bring anything, since bringing something kinda says you're not into Mexican food and would prefer to have your own. But, I guess it doesn't hurt to bring some chips. I'm not sure if your friends are like my family members, who are strictly Mexican, but i've been to most of their parties and for birthday parties, the guests don't have to bring anything other than gifts. And I guess there's no way you can avoid standing out if the rest of the guests are Mexican but that doesn't mean you won't be able to blend in after a bit of intermingling.
