An excellent Mexican tradition, excellent for groups, or even just for two.
The best way to cook the beef is with a standard charcoal grill, but gas works too. Prep and Cook time vary, but usually you can start the charcoal at the beginning of prep and it will be hot by the time you're ready.
TIP: Have the butcher thin slice the roast for you if not already thin sliced, it's much easier and saves a lot of prep time.
In place of the spices listed, you may also use Carne Asada Seasoning, or even Season Salt like Johnny's or Lowery's.
