You will find many vendors on the streets with their grills, chopping customers’ choice of meat (chicken, beef, lamb), seasoning, and grilling it in front of them. Sauce is a combination of onions, mustard, black pepper and jimbo/maggie.
It is most commonly served on a brown paper bag to catch the drippings. You can eat it in a soft tapalapa bread or with rice (less likely).
Afra is also popular dish for beach and birthday parties.
