Slice the skirt steak and then dice it into small bite size pieces.
Place all the marinade ingredients in a blender or food processor blend until smooth.
Place the steak in a large bowl or ziplock bag. Cover with the marinade. Cover and refrigerate for at least 1 hour (but not more than 8 hours).
Preheat the Blackstone griddle over high heat (approximately 450 degrees F). You want the griddle to be hot to get a good sear on the steaks.
Spread the oil out onto the Blackstone grill.
Once the oil is hot, place the steak on the Blackstone grill on top of the oil. Let them cook for 2-3 minutes and do not move them to get a good sear on the steak.
Use a spatula to flip the steaks onto a separate section of the grill. Then cook the steaks for 2-3 more minutes to sear the opposite side of the steaks.
Remove the steak from the griddle and clean it off with a spatula.
Add the corn tortillas and cook them for 1-2 minutes per side to warm them up.
Then it’s time to assemble the tacos. Use 2 tortillas per taco. Spoon the meat mixture onto the tacos.
Serve with your favorite toppings and enjoy!
