You can marinate the beef in a large plastic bag for easy clean up or in a bowl or dish - make sure the meat is covered with the marinade.
Grill on high for best results (around 500°F). If you do not own an outdoor grill, you can make carne asada in the oven under the broiler.
Cooking time is an estimate and depends on the thickness of your cut of beef. Use a meat thermometer for best results.
